You tell them: "In all the commands revealed to me I find nothing which men have been forbidden to eat except carrion and running blood and flesh of the swine for it is unclean, or meat consecrated in the name of some other than God, which is profane. But if one is constrained to eat of these without craving or reverting to it, then surely your Lord is forgiving and kind." 145 We forbade the Jews all animals with claws and the fat of sheep [and goats] and oxen, except what is on their backs and in their intestines and what adheres to their bones. That is the penalty We imposed on them for their disobedience. And We assuredly are true to Our word. 146 So if they deny you, [O Muhammad], say, "Your Lord is the possessor of vast mercy; but His punishment cannot be repelled from the people who are criminals." 147 Those who took partners (in worship) with Allah will say: "If Allah had willed, we would not have taken partners (in worship) with Him, nor would our fathers, and we would not have forbidden anything (against His Will)." Likewise belied those who were before them, (they argued falsely with Allah's Messengers), till they tasted of Our Wrath. Say: "Have you any knowledge (proof) that you can produce before us? Verily, you follow nothing but guess and you do nothing but lie." 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
