Surely (as for) those who disbelieve in the communications of Allah and slay the prophets unjustly and slay those among men who enjoin justice, announce to them a painful chastisement.

And an announcement from Allah and His Messenger to the people on the day of the greater pilgrimage that Allah and His Messenger are free from liability to the idolaters; therefore if you repent, it will be better for you, and if you turn back, then know that you will not weaken Allah; and announce painful punishment to those who disbelieve.

And the chiefs of those who disbelieved from among his people said: He is nothing but a mortal like yourselves who desires that he may have superiority over you, and if Allah had pleased, He could certainly have sent down angels. We have not heard of this among our fathers of yore:

That is because there came to them their messengers with clear arguments, but they said: Shall mortals guide us? So they disbelieved and turned back, and Allah does not stand in need (of anything), and Allah is Self-sufficient, Praised.

And We have not made the wardens of the fire others than angels, and We have not made their number but as a trial for those who disbelieve, that those who have been given the book may be certain and those who believe may increase in faith, and those who have been given the book and the believers may not doubt, and that those in whose hearts is a disease and the unbelievers may say: What does Allah mean by this parable? Thus does Allah make err whom He pleases, and He guides whom He pleases, and none knows the hosts of your Lord but He Himself; and this is naught but a reminder to the mortals.
