(Muhammad), tell them, "I do not find anything which has been made unlawful to eat in what has been revealed to me except carrion, blood flowing from the body, pork [for pork is absolutely filthy] and the flesh of the animals slaughtered without the mention of the name of God. However, in an emergency, when one does not have any intention of rebelling or transgressing against the law, your Lord will be All-forgiving and All-merciful. 145 And to those of Jewry We have forbidden every beast with claws; and of oxen and sheep We have forbidden them the fat of them, save what their backs carry, or their entrails, or what is mingled with bone; that We recompensed them for their insolence; surely We speak truly. 146 If they call you a liar, tell them infinite is the mercy of your Lord; but His vengeance will not be turned back from the sinners. 147 But the idolaters say: "If God had so willed we would not have associated (others with Him), nor would have our fathers, nor would we have forbidden any thing." So had others denied before them, and had to taste Our punishment in the end. Ask them: "Have you any knowledge? Then display it. You follow nothing but conjecture, and are nothing but liars." 148 Say - For Allah's is the final argument - Had He willed He could indeed have guided all of you. 149 Say, "Come, bring your witnesses, who can testify that God forbade [all] this." If they bear witness [falsely], do not bear witness with them; nor yield to the wishes of those who deny Our signs, nor of those who do not believe in the life to come and set up others as equals with their Lord. 150
