Say, "I do not find within that which was revealed to me [anything] forbidden to one who would eat it unless it be a dead animal or blood spilled out or the flesh of swine - for indeed, it is impure - or it be [that slaughtered in] disobedience, dedicated to other than Allah. But whoever is forced [by necessity], neither desiring [it] nor transgressing [its limit], then indeed, your Lord is Forgiving and Merciful." 145 Unto those who are Jews We forbade every animal with claws. And of the oxen and the sheep forbade We unto them the fat thereof save that upon the backs or the entrails, or that which is mixed with the bone. That we awarded them for their rebellion. And lo! we verily are truthful. 146 So, if they accuse you of lying, say, "The mercy of your Lord is all-encompassing. His punishment cannot be averted from sinful men." 147 Those who associate others with Allah in His divinity will now surely say: 'Had Allah willed, neither we nor our forefathers would have associated others with Allah in His divinity, nor would we have declared anything (which Allah did not forbid) as forbidden.' Even so those who had lived before them gave the lie (to the Truth) until they tasted Our chastisement. Tell them: 'Have you any sure knowledge that you can produce before us? In fact you are only following idle fancies, merely conjecturing.' 148 Say: 'To God belongs the argument conclusive; for had He willed, He would have guided you all.' 149 Say, [O Muhammad], "Bring forward your witnesses who will testify that Allah has prohibited this." And if they testify, do not testify with them. And do not follow the desires of those who deny Our verses and those who do not believe in the Hereafter, while they equate [others] with their Lord. 150
