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 how many an angel is there in the heavens whose intercession does not avail at all except after Allah has given permission to whom He pleases and chooses.

Abasement is made to cleave to them wherever they are found, except under a covenant with Allah and a covenant with men, and they have become deserving of wrath from Allah, and humiliation is made to cleave to them; this is because they disbelieved in the communications of Allah and slew the prophets unjustly; this is because they disobeyed and exceeded the limits.
