And (remember) the Day when We shall raise up from each nation a witness (their Messenger), then, those who have disbelieved will not be given leave (to put forward excuses), nor will they be allowed (to return to the world) to repent and ask for Allah's Forgiveness (of their sins, etc.). 84 Once the wrong-doers have beheld the chastisement, neither will it be lightened for them nor will they be granted any respite. 85 And when the idolaters see their associates they will say: 'Our Lord, these are our associates on whom we called other than You' But they will throw back at them saying: 'Surely, you are truly liars' 86 That Day shall they (openly) show (their) submission to Allah; and all their inventions shall leave them in the lurch. 87 For those who disbelieve and debar (men) from the way of Allah, We add doom to doom because they wrought corruption, 88 (O Muhammad), warn them of the coming of a Day when We shall bring forth a witness against them from each community and We shall bring you forth as a witness against them all; (and it is for that purpose that) We sent down the Book to you which makes everything clear, and serves as a guidance and mercy and glad tidings to those who have submitted to Allah. 89
