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 'Then if they give you the lie, say: 'Your Lord is of unbounded mercy; but His punishment shall not be averted from the guilty folk.' 147 Those who associate partners with God will surely say, "Had God pleased, neither we nor our fathers would have served other gods besides Him; nor would we have made anything unlawful." Likewise those who lived before them argued falsely until they came to taste Our punishment! Say, "Have you any knowledge? If so, produce it before us. You follow nothing but conjecture. You are merely guessing." 148 Say: Then Allah's is the conclusive argument; so if He please, He would certainly guide you all. 149 Say: Come, bring your witnesses who can bear witness that Allah forbade (all) this. And if they bear witness, do not thou bear witness with them. Follow thou not the whims of those who deny Our revelations, those who believe not in the Hereafter and deem (others) equal with their Lord. 150
