(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 animals with claws and the fat of sheep [and goats] and oxen, except what is on their backs and in their intestines and what adheres to their bones. That is the penalty We imposed on them for their disobedience. And We assuredly are true to Our word. 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 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: 'Allah alone has the conclusive proof. Had He willed, He would have guided you all' 149 Say, [O Muhammad], "Bring forward your witnesses who will testify that Allah has prohibited this." And if they testify, do not testify with them. And do not follow the desires of those who deny Our verses and those who do not believe in the Hereafter, while they equate [others] with their Lord. 150
