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 When the wrongdoers face their punishment, it shall not be lightened for them, nor shall they be granted any reprieve. 85 And when the polytheists will see their ascribed partners, they will say, “Our Lord! These are our partners whom we used to worship besides You”; so they will strike back at them with the saying, “You are indeed liars!” 86 And they will impart to Allah that Day [their] submission, and lost from them is what they used to invent. 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 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
