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 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 Those who associate partners with God will surely say, "Had God pleased, neither we nor our fathers would have served other gods besides Him; nor would we have made anything unlawful." Likewise those who lived before them argued falsely until they came to taste Our punishment! Say, "Have you any knowledge? If so, produce it before us. You follow nothing but conjecture. You are merely guessing." 148 Say: 'To God belongs the argument conclusive; for had He willed, He would have guided 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
