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 And to those who were Jews We made unlawful every animal having claws, and of oxen and sheep We made unlawful to them the fat of both, except such as was on their backs or the entrails or what was mixed with bones: this was a punishment We gave them on account of their rebellion, and We are surely Truthful. 146 If they call you a liar, tell them infinite is the mercy of your Lord; but His vengeance will not be turned back from the sinners. 147 THOSE who are bent on ascribing divinity to aught beside God will say: "Had God so willed, we would not have ascribed divinity to aught but Him, nor would our forefathers [have done so]; and neither would we have declared as forbidden anything [that He has allowed]." Even so did those who lived before them give the lie to the truth - until they came to taste Our punishment! Say: "Have you any [certain] knowledge which you could proffer to us? You follow but [other people's] conjectures, and you yourselves do nothing but guess." 148 Say: 'To God belongs the argument conclusive; for had He willed, He would have guided you all.' 149 Ask them to call their witness who will testify that God has made certain things unlawful. Even if they do testify, do not testify with them. Do not follow the desires of those who have rejected Our revelations and the pagans who do not believe in the Day of Judgment. 150
