Tell them (O Muhammad!): 'I do not find in what has been revealed to me anything forbidden for anyone who wants to eat unless it is carrion, outpoured blood and the flesh of swine, all of which is unclean; or that which is profane having been slaughtered in a name other than that of Allah. But whosoever is constrained to it by necessity - neither desiring to disobey nor exceeding the limit of necessity - your Lord is surely AllForgiving, All-Compassionate. 145 We forbade the Jews all with undivided hoofs and the fat of sheep and cattle, except what is on their backs and entrails, and what is mixed with their bones. As such We recompensed them for their transgressions. Indeed, We are 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: Then Allah's is the conclusive argument; so if He please, He would certainly guide you all. 149 Say: "Bring forward your witnesses, who can testify that Allah has forbidden this. Then if they testify, testify not you (O Muhammad SAW) with them. And you should not follow the vain desires of such as treat Our Ayat (proofs, evidences, verses, lessons, signs, revelations, etc.) as falsehoods, and such as believe not in the Hereafter, and they hold others as equal (in worship) with their Lord." 150
