Say: 'I do not find, in what is revealed to me, aught forbidden to him who eats thereof except it be carrion, or blood outpoured, or the flesh of swine -- that is an abomination -- or an ungodly thing that has been hallowed to other than God; yet whoso is constrained, not desiring nor transgressing, surely thy Lord is All-forgiving, All-compassionate.' 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 give partners (to Allah) will say: "If Allah had wished, we should not have given partners to Him nor would our fathers; nor should we have had any taboos." So did their ancestors argue falsely, until they tasted of Our wrath. Say: "Have ye any (certain) knowledge? If so, produce it before us. Ye follow nothing but conjecture: ye do nothing but lie." 148 Say, "With Allah is the far-reaching argument. If He had willed, He would 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
