Say: I find not in that which is revealed unto me aught prohibited to an eater that he eat thereof, except it be carrion, or blood poured forth, or swineflesh - for that verily is foul - or the abomination which was immolated to the name of other than Allah. But whoso is compelled (thereto), neither craving nor transgressing, (for him) lo! thy Lord is Forgiving, Merciful. 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, "Final authority belongs only to God. Had He wanted, He would have given you all guidance". 149 Tell them: "Bring your witnesses to testify that God has forbidden this (and this)." Then even if they testify, you should not testify with them; and do not follow the wishes of those who deny Our signs and believe not in the Hereafter, and make others the equal of their Lord. 150
