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 polytheists will now say, “Had Allah willed, we would not have ascribed partners (to Him) nor would have our forefathers, nor would we have forbidden anything”; similarly those before them had denied, till the time they tasted Our punishment; say, “Do you have any knowledge so you can offer it to us? You follow only assumptions and only make guesses.” 148 Say: "With Allah is the perfect proof and argument, (i.e. the Oneness of Allah, the sending of His Messengers and His Holy Books, etc. to mankind), had He so willed, He would indeed have guided you all." 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
