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 of Jewry We have forbidden every beast with claws; and of oxen and sheep We have forbidden them the fat of them, save what their backs carry, or their entrails, or what is mingled with bone; that We recompensed them for their insolence; surely We speak truly. 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 are polytheists will say: If Allah had pleased we would not have associated (aught with Him) nor our fathers, nor would we have forbidden (to ourselves) anything; even so did those before them reject until they tasted Our punishment. Say: Have you any knowledge with you so you should bring it forth to us? You only follow a conjecture and you only tell lies. 148 Say - For Allah's is the final argument - Had He willed He could indeed have guided all of you. 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
