Say thou: I find not in that which hath been revealed unto me aught forbidden unto an eater that eateth thereof, except it be carcass, or blood poured forth, or flesh of swine, for that verily is foul or an abomination over which is invoked the name of other than that of Allah. Then whosoever is driven thereto, neither lusting nor transgressing, verily thy Lord is Forgiving, Merciful. 145 And to those who were Jews We made unlawful every animal having claws, and of oxen and sheep We made unlawful to them the fat of both, except such as was on their backs or the entrails or what was mixed with bones: this was a punishment We gave them on account of their rebellion, and We are surely Truthful. 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 Say: 'To God belongs the argument conclusive; for had He willed, He would have guided you all.' 149 Say: "Bring forward your witnesses who could bear witness that God has forbidden [all] this!" - and if they bear witness [falsely,] do not bear witness with them; and do not follow the errant views of those who have given the lie to Our messages, nor of those who believe not in the life to come, and who regard other powers as their Sustainer's equals! 150
