(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 unto those who are Judaised We forbade every animal with cloven hoof; and of the bullock and the goats We forbade unto them the fat thereof, save that which is borne on their backs or entrails or that which sticketh to the bone. Thus We requited them for their rebellion, and verily We are the Truthful. 146 So if they deny you, [O Muhammad], say, "Your Lord is the possessor of vast mercy; but His punishment cannot be repelled from the people who are criminals." 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: "With Allah is the argument that reaches home: if it had been His will, He could indeed have guided you all." 149 Say: "Bring forward your witnesses to prove that Allah did forbid so and so." If they bring such witnesses, be not thou amongst them: Nor follow thou the vain desires of such as treat our signs as falsehoods, and such as believe not in the Hereafter: for they hold others as equal with their Guardian-Lord. 150
