Say: I do not find in that which has been revealed to me anything forbidden for an eater to eat of except that it be what has died of itself, or blood poured forth, or flesh of swine-- for that surely is unclean-- or that which is a transgression, other than (the name of) Allah having been invoked on it; but whoever is driven to necessity, not desiring nor exceeding the limit, then surely your Lord is Forgiving, 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 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 Those who associated with Allah will say, "If Allah had willed, we would not have associated [anything] and neither would our fathers, nor would we have prohibited anything." Likewise did those before deny until they tasted Our punishment. Say, "Do you have any knowledge that you can produce for us? You follow not except assumption, and you are not but falsifying." 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, "Come, bring your witnesses, who can testify that God forbade [all] this." If they bear witness [falsely], do not bear witness with them; nor yield to the wishes of those who deny Our signs, nor of those who do not believe in the life to come and set up others as equals with their Lord. 150
