Say: 'I do not find, in what is revealed to me, aught forbidden to him who eats thereof except it be carrion, or blood outpoured, or the flesh of swine -- that is an abomination -- or an ungodly thing that has been hallowed to other than God; yet whoso is constrained, not desiring nor transgressing, surely thy Lord is All-forgiving, All-compassionate.' 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 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, "With Allah is the far-reaching argument. If He had willed, He would have guided you all." 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
