Say: 'I find nothing in what has been revealed to me that forbids any one to eat of any food except the dead, running blood, and the flesh of swine for these are unclean and that which has been hallowed in its slaughter to other than Allah. But whoever is constrained to eat of any of these, not intending to sin or transgress, then your Lord is Forgiving, the Most Merciful. 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 So if they give the lie to thee (Muhammad), say: Your Lord is a Lord of All-Embracing Mercy, and His wrath will never be withdrawn from guilty folk. 147 The idolaters will say: 'Had Allah willed, neither we nor our fathers would have associated (idols), nor would we have forbidden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: "To God belongs the consummate argument. Had He willed He would surely have guided all of you aright." 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
