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 When the idolaters see their partners they will call out: "O our Lord, these are the partners we invoked instead of You;" but they will retort: "You are liars." 86 And they will offer God surrender that day, and there shall go astray from them that they were forging. 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
