Say: "I find not in the message received by me by inspiration any (meat) forbidden to be eaten by one who wishes to eat it, unless it be dead meat, or blood poured forth, or the flesh of swine,- for it is an abomination - or, what is impious, (meat) on which a name has been invoked, other than Allah's". But (even so), if a person is forced by necessity, without wilful disobedience, nor transgressing due limits,- thy Lord is Oft-forgiving, Most Merciful. 145 And to those who had Judaized We have forbidden all beasts with claws, and the fat of oxen and sheep except the fat which is either on their backs or their entrails, or that which sticks to the bones. Thus did We requite them for their rebellion. Surely We state the Truth. 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: 'To God belongs the argument conclusive; for had He willed, He would have guided you all.' 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
