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 the unjust will see the punishment, from that time on it will not be lightened for them, nor will they get respite. 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 And they proffer unto Allah submission on that day, and all that they used to invent hath failed them. 87 As for those who disbelieved and barred others from the way of Allah, We shall add further chastisement to their chastisement for all the mischief they did. 88 And on that Day We shall raise up from every nation a witness from their own against them, and We shall bring you (Prophet Muhammad) as a witness against those. And We have sent down to you the Book making everything clear, as a guidance, and mercy, and glad tidings to those who submit. 89
