Say [O Prophet], "In all that has been revealed to me, I do not find a ban on anything to eat, except for carrion, flowing blood and pork, all these being unclean or profane, on which the name of someone other than God has been invoked." But if anyone is forced by necessity, being neither disobedient nor exceeding the limit, then surely your Lord is most forgiving and merciful. 145 And [only] unto those who followed the Jewish faith did We forbid all beasts that have claws; and We forbade unto them the fat of both oxen and sheep, excepting that which is in their backs or entrails or that which is within the bone: thus did We requite them for their evildoing - for, behold, We are true to Our word!" 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 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
