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 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 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: 'To God belongs the argument conclusive; for had He willed, He would have guided you all.' 149 Say, “Bring your witnesses who can testify that Allah has forbidden this”; then if they do testify, O listener (followers of this Prophet) do not bear witness along with them and do not follow the desires of those who deny Our signs, and of those who do not believe in the Hereafter and who ascribed equals to their Lord. 150
