You tell them: "In all the commands revealed to me I find nothing which men have been forbidden to eat except carrion and running blood and flesh of the swine for it is unclean, or meat consecrated in the name of some other than God, which is profane. But if one is constrained to eat of these without craving or reverting to it, then surely your Lord is forgiving and kind." 145 And unto those who are Judaised We forbade every animal with cloven hoof; and of the bullock and the goats We forbade unto them the fat thereof, save that which is borne on their backs or entrails or that which sticketh to the bone. Thus We requited them for their rebellion, and verily We are the Truthful. 146 So, if they cry thee lies, say: 'Your Lord is of mercy all-embracing, and His might will never be turned back from the people of the sinners.' 147 They who are idolaters will say: Had Allah willed, we had not ascribed (unto Him) partners neither had our fathers, nor had we forbidden aught. Thus did those who were before them give the lie (to Allah's messengers) till they tasted of the fear of Us. Say: Have ye any knowledge that ye can adduce for Us? Lo! ye follow naught but an opinion, Lo! ye do but guess. 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: Bring your witnesses who should bear witness that Allah has forbidden this, then if they bear witness, do not bear witness with them; and follow not the low desires of those who reject Our communications and of those who do not believe in the hereafter, and they make (others) equal to their Lord. 150
