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 [only] unto those who followed the Jewish faith did We forbid all beasts that have claws; and We forbade unto them the fat of both oxen and sheep, excepting that which is in their backs or entrails or that which is within the bone: thus did We requite them for their evildoing - for, behold, We are true to Our word!" 146 So, if they accuse you of lying, say, "The mercy of your Lord is all-encompassing. His punishment cannot be averted from sinful men." 147 Those who took partners (in worship) with Allah will say: "If Allah had willed, we would not have taken partners (in worship) with Him, nor would our fathers, and we would not have forbidden anything (against His Will)." Likewise belied those who were before them, (they argued falsely with Allah's Messengers), till they tasted of Our Wrath. Say: "Have you any knowledge (proof) that you can produce before us? Verily, you follow nothing but guess and you do nothing but lie." 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: "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
