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 And when those who have done wrong will behold the torment, it will not be lightened unto them, nor will they be respited. 85 And when those who have associated will behold their associate-gods, they will say: our Lord! yonder are our associate-gods upon whom we have been calling beside Thee, they will proffer them the saying: verily ye are liars. 86 That Day shall they (openly) show (their) submission to Allah; and all their inventions shall leave them in the lurch. 87 Those that disbelieve and bar from the way of God -- them We shall give increase of chastisement upon chastisement, for that they were doing corruption. 88 On the day when We call a witness against every nation from their own people, We will call you, (Muhammad), as a witness against them all. We have sent you the Book which clarifies all matters. It is a guide, a mercy, and glad news to the Muslims. 89
