Tell them (O Muhammad!): 'I do not find in what has been revealed to me anything forbidden for anyone who wants to eat unless it is carrion, outpoured blood and the flesh of swine, all of which is unclean; or that which is profane having been slaughtered in a name other than that of Allah. But whosoever is constrained to it by necessity - neither desiring to disobey nor exceeding the limit of necessity - your Lord is surely AllForgiving, All-Compassionate. 145 And for the Jews We forbade all animals with claws; and forbade them the fat of oxen and sheep except which is on their backs or joined to their intestines or to the bone; We awarded this to them for their rebellion; and indeed, surely, We are truthful. 146 But if they give you the lie, then say: Your Lord is the Lord of All-encompassing mercy; and His punishment cannot be averted from the guilty people. 147 Anon will those who associate say: had God willed, we would not have associated, nor our fathers, neither could we have forbidden aught. Even so belied those before them, until they tasted Our wrath. Say thou: is there with you any authority, that ye may bring unto us? ye but follow your fancy, and only conjecture. 148 Say: "To God belongs the consummate argument. Had He willed He would surely have guided all of you aright." 149 Say: "Bring forward your witnesses to prove that Allah did forbid so and so." If they bring such witnesses, be not thou amongst them: Nor follow thou the vain desires of such as treat our signs as falsehoods, and such as believe not in the Hereafter: for they hold others as equal with their Guardian-Lord. 150
