(Muhammad), tell them, "I do not find anything which has been made unlawful to eat in what has been revealed to me except carrion, blood flowing from the body, pork [for pork is absolutely filthy] and the flesh of the animals slaughtered without the mention of the name of God. However, in an emergency, when one does not have any intention of rebelling or transgressing against the law, your Lord will be All-forgiving and All-merciful. 145 For those who followed the Jewish Law, We forbade every (animal) with undivided hoof, and We forbade them that fat of the ox and the sheep, except what adheres to their backs or their entrails, or is mixed up with a bone: this in recompense for their wilful disobedience: for We are true (in Our ordinances). 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: "With Allah is the argument that reaches home: if it had been His will, He could indeed 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
