Tell them (O Muhammad!): 'I do not find in what has been revealed to me anything forbidden for anyone who wants to eat unless it is carrion, outpoured blood and the flesh of swine, all of which is unclean; or that which is profane having been slaughtered in a name other than that of Allah. But whosoever is constrained to it by necessity - neither desiring to disobey nor exceeding the limit of necessity - your Lord is surely AllForgiving, All-Compassionate. 145 And to those who are Jews We prohibited every animal of uncloven hoof; and of the cattle and the sheep We prohibited to them their fat, except what adheres to their backs or the entrails or what is joined with bone. [By] that We repaid them for their injustice. And indeed, We are truthful. 146 If they belie you, say: 'Your Lord is the Owner of all Encompassing Mercy, but His Might cannot be withheld from the nation, the evildoers' 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: 'To God belongs the argument conclusive; for had He 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
