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 We made unlawful for the Jews all animals with claws or nails, and the fat of the oxen and sheep, except that on their backs or their intestines, or which remains attached to their bones. This was the punishment for their insubordination; and what We say is true. 146 If they call you a liar, tell them infinite is the mercy of your Lord; but His vengeance will not be turned back from the sinners. 147 Those who associate others with Allah in His divinity will now surely say: 'Had Allah willed, neither we nor our forefathers would have associated others with Allah in His divinity, nor would we have declared anything (which Allah did not forbid) as forbidden.' Even so those who had lived before them gave the lie (to the Truth) until they tasted Our chastisement. Tell them: 'Have you any sure knowledge that you can produce before us? In fact you are only following idle fancies, merely conjecturing.' 148 Say: 'Allah alone has the conclusive proof. Had He willed, He would have guided you all' 149 Say: 'Produce your witnesses, those who testify God has forbidden this.' Then if they testify, bear not witness with them; and do not thou follow the caprices of those who cried lies to Our signs, and who believe not in the world to come, and ascribe equals to their Lord. 150
