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 for the Jews We forbade all animals with claws; and forbade them the fat of oxen and sheep except which is on their backs or joined to their intestines or to the bone; We awarded this to them for their rebellion; and indeed, surely, We are 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 Those who took partners (in worship) with Allah will say: "If Allah had willed, we would not have taken partners (in worship) with Him, nor would our fathers, and we would not have forbidden anything (against His Will)." Likewise belied those who were before them, (they argued falsely with Allah's Messengers), till they tasted of Our Wrath. Say: "Have you any knowledge (proof) that you can produce before us? Verily, you follow nothing but guess and you do nothing but lie." 148 Say, "With Allah is the far-reaching argument. If He had willed, He would have guided you all." 149 Say to them: 'Call your witnesses to testify that Allah forbade such-and-such.' Then if they do testify, neither testify with them nor follow the desires of those who have given the lie to Our signs and who do not believe in the Hereafter and set up equals with their Lord. 150
