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 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 On that Day they will offer their submission and all that they had fabricated will have vanished. 87 (As for) those who disbelieve and turn away from Allah's way, We will add chastisement to their chastisement because they made mischief. 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
