Say [O Prophet], "In all that has been revealed to me, I do not find a ban on anything to eat, except for carrion, flowing blood and pork, all these being unclean or profane, on which the name of someone other than God has been invoked." But if anyone is forced by necessity, being neither disobedient nor exceeding the limit, then surely your Lord is most forgiving and merciful. 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 'Then if they give you the lie, say: 'Your Lord is of unbounded mercy; but His punishment shall not be averted from the guilty folk.' 147 Those who took partners (in worship) with Allah will say: "If Allah had willed, we would not have taken partners (in worship) with Him, nor would our fathers, and we would not have forbidden anything (against His Will)." Likewise belied those who were before them, (they argued falsely with Allah's Messengers), till they tasted of Our Wrath. Say: "Have you any knowledge (proof) that you can produce before us? Verily, you follow nothing but guess and you do nothing but lie." 148 Say: 'Allah alone has the conclusive proof. Had He willed, He would have guided you all' 149 Say: "Bring forward your witnesses who could bear witness that God has forbidden [all] this!" - and if they bear witness [falsely,] do not bear witness with them; and do not follow the errant views of those who have given the lie to Our messages, nor of those who believe not in the life to come, and who regard other powers as their Sustainer's equals! 150
