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 If they belie you, say: 'Your Lord is the Owner of all Encompassing Mercy, but His Might cannot be withheld from the nation, the evildoers' 147 The pagans will say, "Had God wanted, we would not have worshipped idols, nor would our fathers, nor would we have made anything unlawful." Others before them had also spoken such lies until they experienced the severity of Our wrath. (Muhammad), ask them, "Do you possess any knowledge? If so, tell us about it. You follow only conjectures and preach falsehood." 148 Say: Then Allah's is the conclusive argument; so if He please, He would certainly guide you all. 149 Say: 'Produce your witnesses, those who testify God has forbidden this.' Then if they testify, bear not witness with them; and do not thou follow the caprices of those who cried lies to Our signs, and who believe not in the world to come, and ascribe equals to their Lord. 150
