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 with undivided hoofs and the fat of sheep and cattle, except what is on their backs and entrails, and what is mixed with their bones. As such We recompensed them for their transgressions. Indeed, We are truthful. 146 But if they give you the lie, then say: Your Lord is the Lord of All-encompassing mercy; and His punishment cannot be averted from the guilty people. 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 to them: 'Call your witnesses to testify that Allah forbade such-and-such.' Then if they do testify, neither testify with them nor follow the desires of those who have given the lie to Our signs and who do not believe in the Hereafter and set up equals with their Lord. 150
