Tell them (O Muhammad!): 'I do not find in what has been revealed to me anything forbidden for anyone who wants to eat unless it is carrion, outpoured blood and the flesh of swine, all of which is unclean; or that which is profane having been slaughtered in a name other than that of Allah. But whosoever is constrained to it by necessity - neither desiring to disobey nor exceeding the limit of necessity - your Lord is surely AllForgiving, All-Compassionate. 145 We made unlawful for the Jews all the claw-footed animals, fat of the cows, sheep and goats except what is found on their backs, intestines and whatever is mixed with their bones. Thus, did We recompense them for their rebellion and We are certainly truthful. 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 The pagans will say, "Had God wanted, we would not have worshipped idols, nor would our fathers, nor would we have made anything unlawful." Others before them had also spoken such lies until they experienced the severity of Our wrath. (Muhammad), ask them, "Do you possess any knowledge? If so, tell us about it. You follow only conjectures and preach falsehood." 148 Say, "God alone has the conclusive proof. If He had willed, He could have guided every one of you." 149 Say thou: here with your witnesses, those who will testify that Allah hath forbidden all this. Then even if they testify, testify thou not with them. And follow thou not the desires of those who belie Our signs and those who believe not in the Hereafter while they equalise others with their Lord. 150
