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 to those who had Judaized We have forbidden all beasts with claws, and the fat of oxen and sheep except the fat which is either on their backs or their entrails, or that which sticks to the bones. Thus did We requite them for their rebellion. Surely We state the Truth. 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 Anon will those who associate say: had God willed, we would not have associated, nor our fathers, neither could we have forbidden aught. Even so belied those before them, until they tasted Our wrath. Say thou: is there with you any authority, that ye may bring unto us? ye but follow your fancy, and only conjecture. 148 Say: 'Allah alone has the conclusive proof. Had He willed, He would have guided you all' 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
