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 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 accuse you of lying, say, "The mercy of your Lord is all-encompassing. His punishment cannot be averted from sinful men." 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: "To God belongs the consummate argument. Had He willed He would surely have guided all of you aright." 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
