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 forbade the Jews all animals with claws and the fat of sheep [and goats] and oxen, except what is on their backs and in their intestines and what adheres to their bones. That is the penalty We imposed on them for their disobedience. And We assuredly are true to Our word. 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if they give the lie to thee (Muhammad), say: Your Lord is a Lord of All-Embracing Mercy, and His wrath will never be withdrawn from guilty folk. 147 Those who took partners (in worship) with Allah will say: "If Allah had willed, we would not have taken partners (in worship) with Him, nor would our fathers, and we would not have forbidden anything (against His Will)." Likewise belied those who were before them, (they argued falsely with Allah's Messengers), till they tasted of Our Wrath. Say: "Have you any knowledge (proof) that you can produce before us? Verily, you follow nothing but guess and you do nothing but lie." 148 Say: 'Allah alone has the conclusive proof. Had He willed, He would have guided you all' 149 Say: Bring your witnesses who should bear witness that Allah has forbidden this, then if they bear witness, do not bear witness with them; and follow not the low desires of those who reject Our communications and of those who do not believe in the hereafter, and they make (others) equal to their Lord. 150
