Say thou: I find not in that which hath been revealed unto me aught forbidden unto an eater that eateth thereof, except it be carcass, or blood poured forth, or flesh of swine, for that verily is foul or an abomination over which is invoked the name of other than that of Allah. Then whosoever is driven thereto, neither lusting nor transgressing, verily thy Lord is Forgiving, Merciful. 145 And unto those who are Judaised We forbade every animal with cloven hoof; and of the bullock and the goats We forbade unto them the fat thereof, save that which is borne on their backs or entrails or that which sticketh to the bone. Thus We requited them for their rebellion, and verily We are the Truthful. 146 So if they belie thee, say thou: Your Lord is Owner of extensive mercy, and His wrath shall not be turned aside from the guilty people, 147 But the idolaters say: "If God had so willed we would not have associated (others with Him), nor would have our fathers, nor would we have forbidden any thing." So had others denied before them, and had to taste Our punishment in the end. Ask them: "Have you any knowledge? Then display it. You follow nothing but conjecture, and are nothing but liars." 148 Say: "With Allah is the perfect proof and argument, (i.e. the Oneness of Allah, the sending of His Messengers and His Holy Books, etc. to mankind), had He so willed, He would indeed have guided you all." 149 Say, "Come, bring your witnesses, who can testify that God forbade [all] this." If they bear witness [falsely], do not bear witness with them; nor yield to the wishes of those who deny Our signs, nor of those who do not believe in the life to come and set up others as equals with their Lord. 150
