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 made unlawful for the Jews all the claw-footed animals, fat of the cows, sheep and goats except what is found on their backs, intestines and whatever is mixed with their bones. Thus, did We recompense them for their rebellion and We are certainly truthful. 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 The idolaters will say: 'Had Allah willed, neither we nor our fathers would have associated (idols), nor would we have forbidden anything. As such, those who have gone before them belied until they tasted Our Might. Say: 'Have you any knowledge you can bring forth to us? You follow nothing but guessing and you are only speakers of conjecture' 148 Say, "God alone has the conclusive proof. If He had willed, He could have guided every one of you." 149 Ask them to call their witness who will testify that God has made certain things unlawful. Even if they do testify, do not testify with them. Do not follow the desires of those who have rejected Our revelations and the pagans who do not believe in the Day of Judgment. 150
