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 to those who had Judaized We have forbidden all beasts with claws, and the fat of oxen and sheep except the fat which is either on their backs or their entrails, or that which sticks to the bones. Thus did We requite them for their rebellion. Surely We state the Truth. 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 Those who are polytheists will say: If Allah had pleased we would not have associated (aught with Him) nor our fathers, nor would we have forbidden (to ourselves) anything; even so did those before them reject until they tasted Our punishment. Say: Have you any knowledge with you so you should bring it forth to us? You only follow a conjecture and you only tell lies. 148 Say, "Final authority belongs only to God. Had He wanted, He would have given you all guidance". 149 Tell them: "Bring your witnesses to testify that God has forbidden this (and this)." Then even if they testify, you should not testify with them; and do not follow the wishes of those who deny Our signs and believe not in the Hereafter, and make others the equal of their Lord. 150
