Pork is forbidden (haram)

Muslims affirm that the flesh of swine is haram, forbidden, on the explicit text of four Quranic passages (2:173, 5:3, 6:145, 16:115) that name pork alongside carrion, blood, and food consecrated to other than God among unlawful things. Because the ruling rests on direct scriptural wording rather than on analogical reasoning (qiyas), classical jurisprudence treats it as settled beyond dispute, among the small set of food rules classed as nass rather than derived by ijtihad, leaving essentially no room for a school to reach a different conclusion the way schools differ over, say, the permissibility of certain seafood or the use of alcohol in medicine.

Exegetes have long asked why the pig specifically was singled out, and the tradition's answer has been divided. Many classical commentators, including al-Razi, proposed the animal's uncleanliness or a health rationale consistent with the fiqh classification of the live pig as najis, ritually impure, a status that also governs contact, such as touching a pig's saliva or hide, not only eating its flesh. The majority position, however, holds that the command needs no discovered reason at all: obedience is owed to the text regardless of whether its wisdom is known, and speculative rationales are offered as edifying, never as the ground of the ruling itself. The Quran's own concession, that necessity lifts the sin for one who does not desire the food or exceed need, is read as confirming rather than softening the rule, since an exception implies the general prohibition it excuses.

This is one of the few dietary rulings on which every school of Sunni and Shia jurisprudence speaks with a single voice, and it functions, in practice, as one of the clearest outward markers of Muslim identity across very different cultures. It sits inside the wider architecture of halal (permitted) and haram (forbidden), and the further category of tayyib, wholesome or pure food, which many scholars read as adding a standard of quality and health on top of bare lawfulness.

Where the schools do disagree is at the margins: whether a derivative product counts as pork once its original substance has been chemically transformed. The Hanafi school generally accepts istihala, transformation, as sufficient to permit something like gelatin once the source material has become, in substance, a different thing, while Shafii and Hanbali jurists have tended to hold that an item of pig origin remains prohibited regardless of processing, a stricter reading that shapes the modern halal certification industry's caution around gelatin, emulsifiers, and enzymes of uncertain origin.

The Islamic ban runs parallel to, but developed independently of, the Jewish judgment that the pig is not kosher. Torah law (Leviticus 11:7) gives an explicit criterion, that the pig has a split hoof but does not chew the cud, and Maimonides later offered a hygienic rationale for the kosher laws generally; normative Islamic scholarship, by contrast, has largely resisted assigning the pig prohibition any single stated reason, preferring to leave it, like much ritual law, a matter of submission rather than explanation.
