Say: 'I find nothing in what has been revealed to me that forbids any one to eat of any food except the dead, running blood, and the flesh of swine for these are unclean and that which has been hallowed in its slaughter to other than Allah. But whoever is constrained to eat of any of these, not intending to sin or transgress, then your Lord is Forgiving, the Most Merciful. 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 So, if they cry thee lies, say: 'Your Lord is of mercy all-embracing, and His might will never be turned back from the people of the sinners.' 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 - For Allah's is the final argument - Had He willed He could indeed have guided all of you. 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
