Say [O Prophet], "In all that has been revealed to me, I do not find a ban on anything to eat, except for carrion, flowing blood and pork, all these being unclean or profane, on which the name of someone other than God has been invoked." But if anyone is forced by necessity, being neither disobedient nor exceeding the limit, then surely your Lord is most forgiving and 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 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 those witnesses of yours who can testify that Allah has forbidden this' If they testify to it, do not testify with them, nor follow the wishes of those who belie Our verses, and disbelieve in the Everlasting Life and ascribe equals to their Lord. 150
