Quran 6:146 — Livestock (Al-An'am)

For those who are Jewish we prohibited animals with undivided hoofs; and of the cattle and sheep we prohibited the fat, except that which is carried on their backs, or in the viscera, or mixed with bones. That was a retribution for their transgressions, and we are truthful.

[6:145] Say, "I do not find in the revelations given to me any food that is prohibited for any eater except: (1) carrion, (2) running blood, (3) the meat* of pigs, for it is contaminated, and (4) the meat of animals blasphemously dedicated to other than GOD." If one is forced (to eat these), without being deliberate or malicious, then your Lord is Forgiver, Most Merciful.

[6:147] If they disbelieve you, then say, "Your Lord possesses infinite mercy, but His retribution is unavoidable for the guilty people."
