Say: I do not find in that which has been revealed to me anything forbidden for an eater to eat of except that it be what has died of itself, or blood poured forth, or flesh of swine-- for that surely is unclean-- or that which is a transgression, other than (the name of) Allah having been invoked on it; but whoever is driven to necessity, not desiring nor exceeding the limit, then surely your Lord is Forgiving, Merciful. 145 And to those of Jewry We have forbidden every beast with claws; and of oxen and sheep We have forbidden them the fat of them, save what their backs carry, or their entrails, or what is mingled with bone; that We recompensed them for their insolence; surely We speak truly. 146 If they call you a liar, tell them infinite is the mercy of your Lord; but His vengeance will not be turned back from the sinners. 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: "[Know,] then, that the final evidence [of all truth] rests with God alone; and had He so willed, He would have guided you all aright. 149 Say thou: here with your witnesses, those who will testify that Allah hath forbidden all this. Then even if they testify, testify thou not with them. And follow thou not the desires of those who belie Our signs and those who believe not in the Hereafter while they equalise others with their Lord. 150
