The Fiqh of Permissibility

Much of the public conversation about whether Muslims should eat meat treats "halal" and "haram" as though they were the only two boxes fiqh has to offer, and as though the boundary between them were drawn once, permanently, by a single verse or hadith. Classical Islamic law is considerably more textured than that. It works with a graduated scale of legal values, a strong background presumption in favour of permissibility, and an entire apparatus for thinking about how a thing that is lawful in itself can nonetheless become inadvisable, discouraged, or even blocked once its context, consequences, or the intention behind it are taken into account. Understanding that apparatus does not settle the ethical debate about modern animal agriculture, but it does change what counts as a serious argument within it — and it exposes some arguments, on every side of the debate, as resting on a thinner grasp of usul al-fiqh than their confidence suggests.

The five ahkam

Classical usul al-fiqh sorts every human act into one of five legal values, known as al-ahkam al-taklifiyya al-khamsa. At one end sits wajib (obligatory), an act whose omission is sinful and whose performance is rewarded; close to it sits mandub or mustahabb (recommended), whose performance is rewarded but whose omission carries no sin. In the middle sits mubah (neutral or permissible), an act that is simply indifferent in the eyes of the law — neither commanded nor discouraged. Toward the forbidden end sits makruh (disliked), an act whose omission is rewarded but whose commission is not sinful, and finally haram (forbidden), an act whose commission is sinful and whose omission is rewarded. The overwhelming majority of ordinary human activity — what one eats for breakfast, which route one walks to work, how one furnishes a house — falls into the wide neutral category of mubah, a fact that is easy to lose sight of in debates that assume every question about food must resolve into a binary of halal or haram.

It is worth being precise about where "meat-eating in general" sits within this scheme, because the five ahkam framework is sometimes deployed loosely by participants on every side of the vegan debate. The permissibility of eating the flesh of animals slaughtered according to the recognised conditions is, in the view of the overwhelming majority of classical and contemporary scholarship, a matter of settled mubah — and some jurists would locate specific instances, such as eating at a wedding feast or accepting hospitality, closer to mandub. What remains genuinely contested is not whether meat-eating as such is lawful, which is not seriously disputed within Sunni or Shi'i fiqh, but whether particular instances of it — meat produced under specific industrial conditions, for instance — might be affected by the surrounding circumstances in ways explored below.

The default of ibaha

A closely related but distinct principle is al-ibaha al-asliyya, the original permissibility of things. The classical legal maxim states it plainly: al-asl fi'l-ashya' al-ibaha, "the default state of things is permissibility," until a specific text establishes otherwise. This maxim applies most clearly to created things and substances — plants, animals, minerals, foodstuffs — rather than to acts of worship, where the reverse presumption typically applies (an act of worship requires positive textual warrant rather than being permissible by default). For food derived from animals, this means the burden of proof lies with anyone wishing to establish a prohibition, not with anyone wishing to establish permissibility. The Qur'an's specification of a comparatively short list of forbidden categories — carrion, blood, swine flesh, and what has been dedicated to other than God (Qur'an 5:3) — is read by the classical tradition as confirming rather than qualifying this default: had the governing presumption been prohibition, one would expect an enumerated list of what is permitted rather than a short list of what is excluded from a broad permission.

This matters for the ethical debate because it shifts where the argumentative weight has to fall. An argument that some form of meat consumption should be avoided on ethical grounds does not need to overturn ibaha to be a serious argument — it can operate entirely within the register of the recommended, the discouraged, or the personally prudent, none of which require unseating the default permissibility of meat as a category. But an argument that goes further, and claims that eating meat as such has become haram, does need to overturn ibaha, and the evidentiary bar for doing so is, by design, considerably higher than the bar for urging caution or restraint.

How a halal thing becomes impermissible

The clearest classical mechanism for showing how something lawful in itself can become problematic through its context is sadd al-dhara'i, usually translated "blocking the means." The underlying logic is straightforward: an act that is neutral or even praiseworthy when considered on its own can be prohibited, or at least discouraged, when it reliably functions as a pathway to something genuinely unlawful. The classical example most often given is the prohibition of certain otherwise permissible sales contracts when they are transparently being used as a device to achieve usury (riba) by another name — the underlying transaction of sale is lawful in the abstract, but the specific structuring of it toward a forbidden end brings it within the scope of prohibition or at least strong disapproval.

Applied to food and animal treatment, sadd al-dhara'i is the principle most often invoked by those who argue that specific practices within modern animal agriculture — rather than meat-eating as such — might warrant restriction. If a particular method of rearing or slaughter reliably produces outcomes the law elsewhere identifies as harms (cruelty to animals, contravention of the Prophetic instruction to sharpen the blade and spare the animal distress, documented harm to workers or to the surrounding environment), then the argument runs that the means, not the underlying eating of meat, is the proper object of restriction. Critics of this move are quick to note that sadd al-dhara'i has classically been applied with considerable caution, precisely because an unrestrained use of the principle threatens to swallow the presumption of ibaha discussed above: almost anything can be said to lead, by some causal chain, to some harm, and the classical jurists who developed the doctrine were careful to require a strong, near-certain, and direct connection between the means and the prohibited end before invoking it, not a speculative or merely possible one.

Makruh tanzihi and makruh tahrimi

The category of makruh, usually rendered simply as "disliked" or "discouraged," is itself internally graded in a way that rarely survives translation into English. The Hanafi school in particular distinguishes makruh tanzihi, a mild dislike close to the neutral mubah end of the scale, from makruh tahrimi, a strong dislike bordering on prohibition and resting on evidence just short of what is required to establish full haram status. The difference is not merely rhetorical. Makruh tanzihi describes acts it is simply better, for reasons of refinement or caution, to avoid — eating garlic or onions before attending the mosque is a standard classical example, tied to a hadith concern for others' comfort rather than to any suggestion of sin. Makruh tahrimi, by contrast, describes acts close enough to a forbidden category that avoiding them is a matter of real religious seriousness, even where the underlying evidence stops short of the certainty (qat'iyya) that full tahrim classically requires.

This distinction gives the tradition a resource that is often missing from popular debate, where the only available categories seem to be "fine" and "forbidden." A scholar or an individual Muslim can coherently hold that eating meat produced under conditions that fall well short of Islamic standards of ihsan toward animals is makruh — even makruh tahrimi, strongly discouraged — without thereby claiming that such meat is haram in the full technical sense that would carry legal and theological consequences (invalidating a sacrifice, for instance, or rendering the eater sinful in the same register as eating carrion). Much of the more careful contemporary writing on factory-farmed meat operates, whether explicitly or not, within this makruh register, and the fiqh of permissibility gives good grounds for taking that register seriously rather than treating it as an evasive halfway house.

Maqasid al-shari'a and the five preserved goods

Behind the detailed rulings of fiqh, classical jurists increasingly articulated a theory of the law's higher objectives, maqasid al-shari'a, most systematically developed by al-Shatibi in the Muwafaqat. The theory holds that the law aims, at its foundation, to preserve five universal goods (al-daruriyyat al-khams): religion (din), life (nafs), intellect ('aql), lineage (nasl), and property (mal). Individual rulings, on this view, are not arbitrary or self-justifying but serve, in aggregate, to protect these goods, and a proper understanding of any specific ruling benefits from asking which of the five it serves and how.

Contemporary arguments about diet frequently invoke hifz al-nafs, the preservation of life — both human life, through arguments about nutrition, disease risk, and the health consequences of particular diets, and, more controversially, animal life, through an extension of the concept some scholars accept and others resist. They also invoke hifz al-mal, the preservation of property or wealth, in arguments about the economic and environmental costs of industrial animal agriculture, and occasionally hifz al-nasl, the preservation of lineage or progeny, in arguments about intergenerational environmental harm. It is important to be honest about the interpretive step involved in each of these extensions. Al-Shatibi's own daruriyyat were formulated with human welfare as their object; extending hifz al-nafs to non-human animal life, while not without supporters among contemporary scholars sympathetic to animal welfare concerns, is an extension rather than a straightforward application of the classical category, and readers should recognise it as a genuinely contested move rather than settled maqasid doctrine.

A different, and rather more careful, route into the same territory is offered by the academic study of Mohsen Javadi and Asghar Masoudi, "Animal Rights from the Islamic Perspective," which does not argue for vegetarianism at all but does argue that animal rights in the Islamic sources are best understood as rights of protection rather than rights of the same kind humans hold. Because an animal cannot itself forgive a wrong done to it or waive a claim on its own behalf, the authors argue, the human duty to feed, water and refrain from harming an animal in one's care is not a debt that can be discharged by the animal's consent, the way a human creditor might release a debtor — it can only be discharged by actually performing it. That is a structural claim about the nature of the obligation rather than a claim about hifz al-nafs specifically, but it supplies a genuinely Islamic, rather than imported, ground for treating animal welfare as a serious and non-negotiable duty within maqasid-based reasoning, distinct from the more contested question of whether animal life belongs among al-Shatibi's own five preserved goods.

Maslaha mursala and 'urf

Two further tools allow fiqh to respond to circumstances the primary texts do not address explicitly. Maslaha mursala, "unrestricted benefit" or "considered welfare," permits jurists to rule on genuinely new cases by reference to the general welfare the law is understood to promote, provided the ruling does not contradict an explicit text and serves a benefit the law would plausibly recognise. 'Urf, custom, is separately recognised as a source jurists may draw on when a text leaves matters to be settled by common practice, and classical fiqh maxims state directly that al-'ada muhakkama, "custom is a governing consideration," and that ruling can shift as custom shifts — taghayyur al-ahkam bi-taghayyur al-azman wa'l-amkina, "rulings change with the change of times and places," a maxim particularly associated with the Hanafi and Maliki traditions and with Ibn Qayyim al-Jawziyya's writing on judicial policy.

These tools are genuinely double-edged in the present debate. Advocates of a more cautious approach to industrial meat point out, reasonably, that the scale, mechanisation, and biological manipulation involved in most contemporary animal agriculture bear so little resemblance to the pastoral and small-scale husbandry the classical jurists knew that treating rulings formed under those older conditions as automatically transferable to the present is itself a kind of category error — exactly the sort of changed circumstance the taghayyur al-ahkam maxim was designed to accommodate. Sceptics reply that the maxim concerns changes in custom affecting matters the law left to 'urf in the first place (contract forms, measures, modes of dress) rather than a licence to revisit settled rulings about the underlying lawfulness of eating animals, which rest on explicit texts rather than on custom, and are therefore not the kind of ruling the maxim was ever meant to unsettle.

Darura, hajah, and necessity's limits

Necessity (darura) and need (hajah) form another pair of tools relevant here, though they usually run in the opposite direction from how they appear in vegan arguments. Classically, darura is invoked to permit what is otherwise forbidden — eating carrion or pork to survive starvation is the paradigm case, governed by the principle that necessities render forbidden things permissible (al-darurat tubih al-mahzurat), but strictly bounded by the further maxim that necessity is measured by its true extent (al-darura tuqaddar bi-qadariha) — one may eat only enough to survive, not indulge. Hajah, a lesser threshold of genuine need rather than life-threatening necessity, is used more broadly in fiqh to justify departures from an otherwise stricter default, for instance in commercial transactions that would not be permitted absent widespread need for them.

Some contemporary writers have tried to invert this apparatus, arguing that because alternatives to meat are now widely available, the traditional darura or hajah that might have justified meat consumption (nutritional necessity, absence of adequate plant-based alternatives in earlier eras) no longer applies, and that meat-eating should revert to a stricter default absent that justification. This inversion runs against the grain of how darura and hajah actually function in usul al-fiqh: they are tools for licensing exceptions to an existing prohibition, not independent sources of prohibition in their own right. The absence of a necessity to eat meat does not, by itself, generate a prohibition on eating it, any more than the absence of a necessity to eat mangoes generates a prohibition on mangoes; that argument would have to be made on entirely separate grounds, returning the debate to the sadd al-dhara'i and maqasid arguments discussed above rather than to darura as such.

An open letter's chain of principles, examined

The anonymous Persian open letter to Shia Muslims discussed elsewhere on this site builds its haram conclusion not from a single verse or hadith but from a chain of classical legal principles applied in sequence to industrial animal agriculture. Because the letter is advocacy rather than a ruling from any named jurist or hawza body, and because it explicitly calls its own conclusion a personally "deduced" verdict, the honest way to engage it is to examine each link in the chain on its own terms rather than to accept or dismiss the conclusion wholesale.

La darar wa la dirar ("no harm and no reciprocating harm") is a genuine and widely accepted legal maxim, used across both Sunni and Shi'i fiqh to justify restricting an otherwise permissible act where it causes real harm. The letter invokes it via a list of health harms discussed on the Halal and Tayyib page, several of which are overstated relative to the evidence. Even setting that aside, la darar has classically been applied to specific, demonstrable, direct harms — usury structured as sale, a neighbour's wall endangering a shared property — rather than to a general, population-level health-and-environment case against an entire category of food; extending it that far is a considerably larger step than the maxim's classical applications, and critics reasonably ask why it would stop short of covering sugar, driving, or any number of other widespread but harmful practices.

The prohibition of idha' (causing an animal unnecessary pain) rests on firmer and more direct textual ground: hadiths on ihsan in slaughter, the prohibition of striking an animal's face, and the reports on mutilation and cruelty gathered on the Javadi–Masoudi study's own account are not in serious dispute. Where the letter's use of idha' is more contestable is in its move from specific, well-attested practices — caging, debeaking, forced repeated calving — to a blanket verdict on the resulting food itself; the classical material on idha' addresses the treatment of the animal as an act in its own right, and it is a further, separate argumentative step to conclude that food produced somewhere upstream of a proven instance of idha' is thereby rendered haram for the eventual consumer, rather than that the idha' itself is wrong and should be stopped at its source.

I'ana 'ala al-ithm (assisting in wrongdoing) is the letter's bridge from the producer's wrongdoing to the consumer's culpability: every purchase, on this reading, finances the cage, the debeaking, the forced calving. The principle itself is sound and well established. Its difficulty here is one of degree and directness rather than validity: i'ana 'ala al-ithm has classically been applied most confidently to fairly direct assistance (handing a weapon to someone about to commit murder, knowingly holding stolen goods), and jurists have generally been cautious about extending it to attenuated, many-steps-removed participation in a large economic system, precisely because almost every purchase in a modern economy can be traced back through some chain of wrongdoing somewhere if the chain is drawn long enough. That caution does not refute the letter's argument, but it does mean the argument needs to show why animal agriculture's chain is different in kind, not merely present, from the countless other supply chains a consumer is implicated in.

Al-hukm yadur ma'a al-mawdu' wujudan wa 'adaman ("the ruling turns on its subject matter, existing or ceasing with it") is the letter's most structurally important move, and the most interesting one on its own fiqh terms. If the classical permission to eat meat was really a ruling about a healthy, freely-moving animal killed by an individual, careful slaughter, then a confined, chronically stressed, pharmaceutically altered animal might genuinely be a different mawdu' to which the old ruling does not automatically transfer. This is not an absurd argument, and it echoes the taghayyur al-ahkam discussion above. But it proves less than the letter wants it to: the classical rulings on lawful meat turn principally on species and method of slaughter, not on a detailed specification of the animal's prior living conditions, so it is not obvious that those conditions are part of the ruling's mawdu' at all rather than a separate question (of welfare and idha') governed by its own, distinct principles. A change in living conditions may well be religiously significant without being the kind of change that alters the mawdu' of the permission to eat the animal's meat once lawfully slaughtered.

Ihtiyat (precaution) is the letter's fallback where its other principles do not by themselves compel abstention: where there is genuine doubt about harm or wrongdoing, caution counsels avoidance. Ihtiyat is a real and respected feature of Shi'i legal reasoning, particularly in matters of worship, but it is a personal counsel of caution, not a mechanism for generating a public ruling of prohibition; a jurist can recommend ihtiyat to someone already uncertain of their own position without thereby declaring the underlying act haram for everyone, which is precisely the distinction between wara' and tahrim explored at the end of this page.

The tobacco analogy the letter draws — smoking was unknown to the early jurists and was later ruled forbidden once its harms became clear, so meat and dairy could follow the same path — is the clearest illustration of taghayyur al-ahkam bi taghayyur al-zaman in the letter's own argument, and it is a fair analogy as far as it goes: rulings genuinely can respond to newly established harms. Where the analogy strains is that tobacco's prohibition, where jurists have issued it, rests on a food or substance with no independent nutritional or Qur'anically-endorsed role and a harm profile that is comparatively undisputed and directly caused by the act of consumption itself; meat and dairy, by contrast, are named foods within a category the Qur'an explicitly and repeatedly describes as halal and tayyib, with contested rather than undisputed harms, and with the alleged harm arising from the method of production rather than being intrinsic to the substance consumed. The analogy invites the comparison; it does not by itself carry the weight of transferring tobacco's fate to meat.

Taken together, the chain shows a piece of advocacy reasoning seriously with real fiqh tools rather than simply asserting a conclusion — which is more than can be said for a great deal of popular writing on this subject, on every side. It does not show that the conclusion follows as tightly as the letter presents it: several of the individual links are genuine principles stretched somewhat further than their classical applications, and the cumulative chain is only as strong as its weakest link, not the sum of all of them. See the discussion of the letter itself for its fuller argument and its own closing appeal.

Usul debate: does the subject matter change?

The letter's al-hukm-yadur argument, sketched above, rests on a genuine and long-running usuli discussion worth setting out more fully, because it is the single most sophisticated piece of legal reasoning in the letter and the one most likely to be mishandled by readers on either side. The underlying maxim, al-hukm yadur ma'a mawdu'ihi wujudan wa 'adaman — "the ruling revolves with its subject matter, coming into being and ceasing with it" — is not a slogan invented for this debate. It is discussed at length in the classical and modern usul al-fiqh literature, including al-Shaykh al-Ansari's Fara'id al-Usul and al-Akhund al-Khurasani's Kifayat al-Usul, both foundational texts for how a mujtahid identifies exactly what a given ruling is actually about before applying it to a new case. Muhammad Husayn al-Na'ini's usul writings, transmitted through his students' lecture notes, sharpen the point further: a ruling is only as stable as the description of its subject, and if the thing being described changes in a way that is relevant to why the ruling was given in the first place, the old ruling simply does not extend to the new thing — not because the law has changed, but because the mawdu' has. Both Ruhollah Khomeini and Muhammad Baqir al-Sadr, in their own usul teaching (al-Sadr's Durus fi 'Ilm al-Usul remains a standard modern seminary text), work with versions of the same distinction between the fixed content of a divine ruling and the variable, empirically determined facts about the world to which it is applied. The letter also invokes a saying attributed to Imam Ja'far al-Sadiq,'alayna ilqa' al-usul wa 'alaykum al-tafri' — "upon us [the Imams] rests the statement of principles, and upon you [the community and its jurists] rests their application to particular cases" — as textual support for treating the identification of a changed mawdu' as squarely within the jurist's remit rather than a matter closed by the original texts.

None of this is disputed as usul theory. What is very much open is whether the specific empirical claim the letter makes — that an industrially reared, confined, and rapidly slaughtered animal is a different mawdu' from the animal the classical rulings on lawful meat had in view — actually holds up. The classical permission to eat meat attaches primarily to species and to a validly performed slaughter, not to a certificate about the animal's earlier housing, and a mujtahid could reasonably reply that welfare conditions are a real but separate concern (governed by idha' and ihsan, discussed elsewhere on this site) rather than a component of the mawdu' that the original permission was actually about. Whether the subject truly changed enough to move the ruling is exactly the kind of question the letter itself says belongs to a qualified jurist applying ijtihad to the facts, not to a general reader, an anonymous pamphlet, or a website — this page can lay out the argument's structure honestly but cannot adjudicate it.

The tobacco analogy, examined more closely. The letter's clearest illustration of a changed-subject argument succeeding in practice is tobacco. Smoking was unknown in the Prophet's ﷺ era; no verse or hadith names it; and for centuries jurists who considered it at all tended to treat it as a matter of mubah or, at most, makruh. Once epidemiological evidence of serious, well-established harm accumulated, many contemporary jurists across both Sunni and Shi'i scholarship revised their position, some reaching tahrim, precisely because a previously undetermined empirical fact (does this substance reliably damage health?) had been settled in a way that engaged existing principles like la darar. The letter uses this history to argue that meat and dairy could, in principle, follow the same trajectory once industrial harms are established. The analogy is fair as an illustration that rulings can track newly discovered facts; it is considerably weaker as an argument for meat and dairy specifically, because tobacco carried no independent nutritional value and no explicit Qur'anic endorsement, whereas meat and dairy are named among the tayyibat, and the harms alleged against them remain genuinely contested rather than settled the way tobacco's health effects now are.

Taqdim al-aham 'ala al-muhimm (giving precedence to the weightier interest over the lesser one) supplies the letter's answer to an obvious objection: even granting real harms in animal agriculture, why should avoiding them outweigh the nutritional, economic, social and religious value long attached to eating meat? The principle itself is an accepted tool for resolving genuine conflicts between two legitimate interests that cannot both be fully honoured at once, and the letter applies it by arguing that animal suffering and public health, on its account, are the weightier interest. The difficulty is that taqdim al-aham presupposes an agreed ranking of the competing interests, and that ranking is precisely what is contested here: a jurist who weighs the tradition's endorsement of meat, its role in ritual (sacrifice, 'aqiqa, udhiyya) and ordinary nutrition differently from the letter will reach the opposite conclusion using the identical principle, which means the maxim organises the debate rather than settling it.

Ihtiyat and the shubha tahrimiyya reply. Where the letter cannot show a settled harm, it falls back on precaution in the face of doubtful prohibition (al-ihtiyat fi al-shubha al-tahrimiyya): if there is a live possibility that a given product involves forbidden treatment somewhere upstream, caution counsels avoiding it. The standard juristic reply, made by scholars who take the letter's other arguments seriously, is that the shari'a has never made lawful use conditional on a consumer personally auditing an entire supply chain; the presumption of lawfulness attaching to a Muslim or People-of-the- Book slaughterer's declared tasmiyah, and to goods sold in a Muslim market without established taint (a principle sometimes summarised as asalat al-sihha, the presumption of a transaction's validity), exists precisely to spare ordinary believers from exactly this kind of paralysis. Ihtiyat remains available to any individual who wants to adopt it as personal practice; it is a different matter to present it as a reason everyone must abstain, which returns to the wara'-versus-tahrim distinction discussed at the end of this page. Readers who want to see how this whole chain of argument fits into the wider case for and against are pointed to the full step-by-step walkthrough of the argument.

The danger of forbidding what is halal

Any serious treatment of this territory has to reckon honestly with a cluster of Qur'anic verses that scholars across the theological spectrum treat as establishing an unusually severe warning: the sin of declaring forbidden what God has not forbidden is treated, in these texts, as at least as serious as declaring permitted what God has forbidden.

The third of these verses is theologically significant precisely because of its addressee: it rebukes the Prophet ﷺ himself, in a matter of purely personal and arguably praiseworthy self-restraint (traditionally understood to relate either to a vow concerning honey or to a personal commitment made out of consideration for a wife), for a form of self-imposed prohibition that the verse indicates was not his to make unilaterally, however good his intention. Classical exegetes draw from this a principle with obvious force for the present debate: personal scruple, however sincere or well-motivated, is not the same thing as legal prohibition, and collapsing the two — treating one's own considered avoidance of something as though it amounted to a general ruling that the thing itself is haram — is precisely the move these verses warn against.

It would be a mistake, however, to read these verses as foreclosing every form of dietary caution or ethical argument about meat, and a fair presentation should say so plainly. The verses address declaring something haram without warrant — inventing a legal prohibition God has not established. They do not address, and are not obviously aimed at, arguments that operate at the level of makruh, personal wara' (scrupulous piety), maqasid-based caution about specific harmful practices, or the sadd al-dhara'i arguments discussed above, none of which claim that the underlying category of meat has become haram as such. The verses are, nonetheless, a serious and legitimate constraint on the strongest form of vegan argument — the claim that eating meat is now simply haram — and any presentation of that argument that fails to grapple with 6:140, 10:59 and 66:1 is, on this point, incomplete. Advocates of the strongest form of that argument have generally responded not by disputing the verses' force but by arguing that they are not making a claim of tahrim at all, only a claim about which specific practices amount to genuinely unlawful means under sadd al-dhara'i — a response that, whatever its merits, at least engages the constraint rather than ignoring it.

Personal resolve versus general ruling

The final distinction the fiqh of permissibility supplies, and perhaps the most practically useful one for readers trying to work out what to do with their own plates, is between azima and rukhsa, and between both of these and wara'. Azima refers to the standard, default ruling that applies generally; rukhsa refers to a licensed concession available under specified circumstances. Wara', by contrast, is not a legal category at all but a spiritual disposition — scrupulous caution that leads an individual to avoid even some things that are unambiguously permissible, out of a desire to stay well clear of anything that might be doubtful, burdensome to others, or spiritually coarsening. The Prophet's ﷺ own reported practice included instances of voluntarily forgoing permissible things without ever suggesting they were forbidden to others, and the broader Sufi and ascetic tradition, discussed further on the Scholarly Voices page, developed wara' into an entire ethical vocabulary of personal restraint that operates alongside, rather than instead of, the ordinary rulings of fiqh.

This gives a Muslim drawn toward vegetarianism or veganism a coherent and traditionally grounded way to frame that choice: as an exercise of wara', a personal azima adopted out of ethical conviction about animal welfare, environmental harm, or spiritual discipline, entirely compatible with acknowledging that the general ruling (the azima of the law, in the technical sense) continues to treat meat as lawful for those who do not share that conviction or who judge the underlying concerns differently. The fiqh of permissibility does not require choosing between these two things. It asks only that the two registers — personal scruple and public legal claim — not be quietly merged into one, since it is precisely that merger the Qur'an's sharpest warnings on this subject are concerned to prevent.
