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 And for the Jews We forbade all animals with claws; and forbade them the fat of oxen and sheep except which is on their backs or joined to their intestines or to the bone; We awarded this to them for their rebellion; and indeed, surely, We are truthful. 146 So, if they accuse you of lying, say, "The mercy of your Lord is all-encompassing. His punishment cannot be averted from sinful men." 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, "With Allah is the far-reaching argument. If He had willed, He would have guided you all." 149 Say: 'Bring those witnesses of yours who can testify that Allah has forbidden this' If they testify to it, do not testify with them, nor follow the wishes of those who belie Our verses, and disbelieve in the Everlasting Life and ascribe equals to their Lord. 150
