(Muhammad), tell them, "I do not find anything which has been made unlawful to eat in what has been revealed to me except carrion, blood flowing from the body, pork [for pork is absolutely filthy] and the flesh of the animals slaughtered without the mention of the name of God. However, in an emergency, when one does not have any intention of rebelling or transgressing against the law, your Lord will be All-forgiving and All-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 Those who associate partners with God will surely say, "Had God pleased, neither we nor our fathers would have served other gods besides Him; nor would we have made anything unlawful." Likewise those who lived before them argued falsely until they came to taste Our punishment! Say, "Have you any knowledge? If so, produce it before us. You follow nothing but conjecture. You are merely guessing." 148 Say, "God alone has the conclusive proof. If He had willed, He could have guided every one of you." 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
