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 For those who followed the Jewish Law, We forbade every (animal) with undivided hoof, and We forbade them that fat of the ox and the sheep, except what adheres to their backs or their entrails, or is mixed up with a bone: this in recompense for their wilful disobedience: for We are true (in Our ordinances). 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 They who are idolaters will say: Had Allah willed, we had not ascribed (unto Him) partners neither had our fathers, nor had we forbidden aught. Thus did those who were before them give the lie (to Allah's messengers) till they tasted of the fear of Us. Say: Have ye any knowledge that ye can adduce for Us? Lo! ye follow naught but an opinion, Lo! ye do but guess. 148 'Then say to them: '(As against your argument) Allah's is the conclusive argument. Surely, had He willed, He would have guided you all to the Truth. 149 Say, [O Muhammad], "Bring forward your witnesses who will testify that Allah has prohibited this." And if they testify, do not testify with them. And do not follow the desires of those who deny Our verses and those who do not believe in the Hereafter, while they equate [others] with their Lord. 150
