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 We made unlawful for the Jews all the claw-footed animals, fat of the cows, sheep and goats except what is found on their backs, intestines and whatever is mixed with their bones. Thus, did We recompense them for their rebellion and We are certainly truthful. 146 If they accuse thee of falsehood, say: "Your Lord is full of mercy all-embracing; but from people in guilt never will His wrath be turned back. 147 The pagans will say, "Had God wanted, we would not have worshipped idols, nor would our fathers, nor would we have made anything unlawful." Others before them had also spoken such lies until they experienced the severity of Our wrath. (Muhammad), ask them, "Do you possess any knowledge? If so, tell us about it. You follow only conjectures and preach falsehood." 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: "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
