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 Unto those who are Jews We forbade every animal with claws. And of the oxen and the sheep forbade We unto them the fat thereof save that upon the backs or the entrails, or that which is mixed with the bone. That we awarded them for their rebellion. And lo! we verily 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 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, “Then only Allah’s argument is the complete one; so had He willed, He would have guided you all.” 149 Say, [O Muhammad], "Bring forward your witnesses who will testify that Allah has prohibited this." And if they testify, do not testify with them. And do not follow the desires of those who deny Our verses and those who do not believe in the Hereafter, while they equate [others] with their Lord. 150
