Say: I do not find in that which has been revealed to me anything forbidden for an eater to eat of except that it be what has died of itself, or blood poured forth, or flesh of swine-- for that surely is unclean-- or that which is a transgression, other than (the name of) Allah having been invoked on it; but whoever is driven to necessity, not desiring nor exceeding the limit, then surely your Lord is Forgiving, Merciful. 145 And to those of Jewry We have forbidden every beast with claws; and of oxen and sheep We have forbidden them the fat of them, save what their backs carry, or their entrails, or what is mingled with bone; that We recompensed them for their insolence; surely We speak truly. 146 But if they give you the lie, then say: Your Lord is the Lord of All-encompassing mercy; and His punishment cannot be averted from the guilty people. 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 thou: here with your witnesses, those who will testify that Allah hath forbidden all this. Then even if they testify, testify thou not with them. And follow thou not the desires of those who belie Our signs and those who believe not in the Hereafter while they equalise others with their Lord. 150
