Why Islam Forbids Pork

The flesh of swine is forbidden to Muslims. The Qur'an states this four times, always in a short list alongside carrion, blood, and animals slaughtered in the name of other than Allah. It is a clear, unambiguous ruling on which all Sunni scholars agree, with an exception for genuine necessity.

In one of the four passages the Qur'an describes swine's flesh with a single word: rijs — impure, filthy. That is the extent of the stated reason. The Qur'an does not mention disease, parasites or hygiene. Commentators such as Ibn Kathir explain the prohibition as it stands, without adding medical speculation.

This matters. It would be easy to build a case around trichinosis or the pig's diet, and many have. But those arguments make the ruling hostage to farming practices — cook the meat well, raise the pig cleanly, and the argument dissolves. The ruling does not dissolve. Muslims did not stop eating pork because of a parasite, and they would not start again if the parasite were eradicated.

This prohibition is not unique to Islam. The Torah forbids the pig to the Children of Israel, and observant Jews keep that law today. Islam sees itself as continuous with the earlier revelations on this point, not as innovating.

Because pork is the clearest example of a principle that runs through all of Islam's boundaries. A Muslim who has established that the Qur'an is from Allah does not need to know why swine is impure in order to leave it alone. The ruling is known; the wisdom is Allah's. Obeying without the reason is not blind — the seeing was done when the source was examined.

If the abstinence has health benefits — and it may — a Muslim receives them gratefully. But that is not the transaction. The transaction is trust.
