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 For those who followed the Jewish Law, We forbade every (animal) with undivided hoof, and We forbade them that fat of the ox and the sheep, except what adheres to their backs or their entrails, or is mixed up with a bone: this in recompense for their wilful disobedience: for We are true (in Our ordinances). 146 So, if they cry thee lies, say: 'Your Lord is of mercy all-embracing, and His might will never be turned back from the people of the sinners.' 147 The polytheists will now say, “Had Allah willed, we would not have ascribed partners (to Him) nor would have our forefathers, nor would we have forbidden anything”; similarly those before them had denied, till the time they tasted Our punishment; say, “Do you have any knowledge so you can offer it to us? You follow only assumptions and only make guesses.” 148 Say: "With Allah is the argument that reaches home: if it had been His will, He could indeed have guided you all." 149 Ask them to call their witness who will testify that God has made certain things unlawful. Even if they do testify, do not testify with them. Do not follow the desires of those who have rejected Our revelations and the pagans who do not believe in the Day of Judgment. 150
