Say [O Prophet]: "In all that has been revealed unto me, I do not find anything forbidden to eat, if one wants to eat thereof, unless it be carrion, or blood poured forth, or the flesh of swine - for that, behold, is loathsome - or a sinful offering over which any name other than God's has been invoked. But if one is driven by necessity - neither coveting it nor exceeding his immediate need - then [know that,] behold, thy Sustainer is much-forgiving, a dispenser of grace." 145 We made unlawful for the Jews all animals with claws or nails, and the fat of the oxen and sheep, except that on their backs or their intestines, or which remains attached to their bones. This was the punishment for their insubordination; and what We say is true. 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 Anon will those who associate say: had God willed, we would not have associated, nor our fathers, neither could we have forbidden aught. Even so belied those before them, until they tasted Our wrath. Say thou: is there with you any authority, that ye may bring unto us? ye but follow your fancy, and only conjecture. 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
