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 with undivided hoofs and the fat of sheep and cattle, except what is on their backs and entrails, and what is mixed with their bones. As such We recompensed them for their transgressions. Indeed, We are truthful. 146 And if they give thee the lie, say: "Limitless is your Sustainer in His grace; but His punishment shall not be averted from people who are lost in sin." 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: Then Allah's is the conclusive argument; so if He please, He would certainly guide 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
