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 And to those who are Jews We prohibited every animal of uncloven hoof; and of the cattle and the sheep We prohibited to them their fat, except what adheres to their backs or the entrails or what is joined with bone. [By] that We repaid them for their injustice. And indeed, 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 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, "Final authority belongs only to God. Had He wanted, He would have given you all guidance". 149 Say: "Bring forward your witnesses who could bear witness that God has forbidden [all] this!" - and if they bear witness [falsely,] do not bear witness with them; and do not follow the errant views of those who have given the lie to Our messages, nor of those who believe not in the life to come, and who regard other powers as their Sustainer's equals! 150
