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 are unjust shall see the chastisement, it shall not be lightened for them, nor shall they be respited. 85 And when the idolaters behold their associates, they shall say, 'Our Lord, these are our associates on whom we called apart from Thee.' They will fling back at them the saying, 'Surely, you are truly liars.' 86 That Day shall they (openly) show (their) submission to Allah; and all their inventions shall leave them in the lurch. 87 The disbelievers who had created obstacles in the way leading to God will face manifold torments as a result of their evil deeds. 88 And [mention] the Day when We will resurrect among every nation a witness over them from themselves. And We will bring you, [O Muhammad], as a witness over your nation. And We have sent down to you the Book as clarification for all things and as guidance and mercy and good tidings for the Muslims. 89
