Say: "I find not in the message received by me by inspiration any (meat) forbidden to be eaten by one who wishes to eat it, unless it be dead meat, or blood poured forth, or the flesh of swine,- for it is an abomination - or, what is impious, (meat) on which a name has been invoked, other than Allah's". But (even so), if a person is forced by necessity, without wilful disobedience, nor transgressing due limits,- thy Lord is Oft-forgiving, Most Merciful. 145 And for the Jews We forbade all animals with claws; and forbade them the fat of oxen and sheep except which is on their backs or joined to their intestines or to the bone; We awarded this to them for their rebellion; and indeed, surely, We are 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 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: 'Allah alone has the conclusive proof. Had He 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
