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 So if they give the lie to thee (Muhammad), say: Your Lord is a Lord of All-Embracing Mercy, and His wrath will never be withdrawn from guilty folk. 147 But the idolaters say: "If God had so willed we would not have associated (others with Him), nor would have our fathers, nor would we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 consummate argument. Had He willed He would surely have guided all of you aright." 149 Say: "Bring forward your witnesses to prove that Allah did forbid so and so." If they bring such witnesses, be not thou amongst them: Nor follow thou the vain desires of such as treat our signs as falsehoods, and such as believe not in the Hereafter: for they hold others as equal with their Guardian-Lord. 150
