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 unto those who are Jews, We forbade every (animal) with undivided hoof, and We forbade them the fat of the ox and the sheep except what adheres to their backs or their entrails, or is mixed up with a bone. Thus We recompensed them for their rebellion [committing crimes like murdering the Prophets, eating of Riba (usury), etc.]. And verily, We are Truthful. 146 If they (Jews) belie you (Muhammad SAW) say you: "Your Lord is the Owner of Vast Mercy, and never will His Wrath be turned back from the people who are Mujrimun (criminals, polytheists, sinners, etc.)." 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: "With Allah is the perfect proof and argument, (i.e. the Oneness of Allah, the sending of His Messengers and His Holy Books, etc. to mankind), had He so willed, He would indeed have guided you all." 149 Say, [O Muhammad], "Bring forward your witnesses who will testify that Allah has prohibited this." And if they testify, do not testify with them. And do not follow the desires of those who deny Our verses and those who do not believe in the Hereafter, while they equate [others] with their Lord. 150
