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 For those who followed the Jewish Law, We forbade every (animal) with undivided hoof, and We forbade them that fat of the ox and the sheep, except what adheres to their backs or their entrails, or is mixed up with a bone: this in recompense for their wilful disobedience: for We are true (in Our ordinances). 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 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, "God alone has the conclusive proof. If He had willed, He could have guided every one of you." 149 Say: 'Bring those witnesses of yours who can testify that Allah has forbidden this' If they testify to it, do not testify with them, nor follow the wishes of those who belie Our verses, and disbelieve in the Everlasting Life and ascribe equals to their Lord. 150
