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 And unto those who are Judaised We forbade every animal with cloven hoof; and of the bullock and the goats We forbade unto them the fat thereof, save that which is borne on their backs or entrails or that which sticketh to the bone. Thus We requited them for their rebellion, and verily We are the Truthful. 146 So, if they accuse you of lying, say, "The mercy of your Lord is all-encompassing. His punishment cannot be averted from sinful men." 147 The polytheists will now say, “Had Allah willed, we would not have ascribed partners (to Him) nor would have our forefathers, nor would we have forbidden anything”; similarly those before them had denied, till the time they tasted Our punishment; say, “Do you have any knowledge so you can offer it to us? You follow only assumptions and only make guesses.” 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
