Say: 'I do not find, in what is revealed to me, aught forbidden to him who eats thereof except it be carrion, or blood outpoured, or the flesh of swine -- that is an abomination -- or an ungodly thing that has been hallowed to other than God; yet whoso is constrained, not desiring nor transgressing, surely thy Lord is All-forgiving, All-compassionate.' 145 We made unlawful for the Jews all animals with claws or nails, and the fat of the oxen and sheep, except that on their backs or their intestines, or which remains attached to their bones. This was the punishment for their insubordination; and what We say is true. 146 'Then if they give you the lie, say: 'Your Lord is of unbounded mercy; but His punishment shall not be averted from the guilty folk.' 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 'Then say to them: '(As against your argument) Allah's is the conclusive argument. Surely, had He willed, He would have guided you all to the Truth. 149 Ask them to call their witness who will testify that God has made certain things unlawful. Even if they do testify, do not testify with them. Do not follow the desires of those who have rejected Our revelations and the pagans who do not believe in the Day of Judgment. 150
