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 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 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 But the idolaters say: "If God had so willed we would not have associated (others with Him), nor would have our fathers, nor would we have forbidden any thing." So had others denied before them, and had to taste Our punishment in the end. Ask them: "Have you any knowledge? Then display it. You follow nothing but conjecture, and are nothing but liars." 148 Say - For Allah's is the final argument - Had He willed He could indeed have guided all of you. 149 Say: "Bring forward your witnesses, who can testify that Allah has forbidden this. Then if they testify, testify not you (O Muhammad SAW) with them. And you should not follow the vain desires of such as treat Our Ayat (proofs, evidences, verses, lessons, signs, revelations, etc.) as falsehoods, and such as believe not in the Hereafter, and they hold others as equal (in worship) with their Lord." 150
