Say [O Prophet]: "In all that has been revealed unto me, I do not find anything forbidden to eat, if one wants to eat thereof, unless it be carrion, or blood poured forth, or the flesh of swine - for that, behold, is loathsome - or a sinful offering over which any name other than God's has been invoked. But if one is driven by necessity - neither coveting it nor exceeding his immediate need - then [know that,] behold, thy Sustainer is much-forgiving, a dispenser of grace." 145 And to those who had Judaized We have forbidden all beasts with claws, and the fat of oxen and sheep except the fat which is either on their backs or their entrails, or that which sticks to the bones. Thus did We requite them for their rebellion. Surely We state the Truth. 146 If they accuse thee of falsehood, say: "Your Lord is full of mercy all-embracing; but from people in guilt never will His wrath be turned back. 147 They who are idolaters will say: Had Allah willed, we had not ascribed (unto Him) partners neither had our fathers, nor had we forbidden aught. Thus did those who were before them give the lie (to Allah's messengers) till they tasted of the fear of Us. Say: Have ye any knowledge that ye can adduce for Us? Lo! ye follow naught but an opinion, Lo! ye do but guess. 148 Say, "God alone has the conclusive proof. If He had willed, He could have guided every one of you." 149 Say, [O Muhammad], "Bring forward your witnesses who will testify that Allah has prohibited this." And if they testify, do not testify with them. And do not follow the desires of those who deny Our verses and those who do not believe in the Hereafter, while they equate [others] with their Lord. 150
