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 They reject you. (Muhammad), tell them, "Your Lord's mercy is completely overwhelming, but no one can save the sinful from His wrath." 147 Those who associated with Allah will say, "If Allah had willed, we would not have associated [anything] and neither would our fathers, nor would we have prohibited anything." Likewise did those before deny until they tasted Our punishment. Say, "Do you have any knowledge that you can produce for us? You follow not except assumption, and you are not but falsifying." 148 Say: Then Allah's is the conclusive argument; so if He please, He would certainly guide you all. 149 Say: "Bring forward your witnesses who could bear witness that God has forbidden [all] this!" - and if they bear witness [falsely,] do not bear witness with them; and do not follow the errant views of those who have given the lie to Our messages, nor of those who believe not in the life to come, and who regard other powers as their Sustainer's equals! 150
