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 they who were bent on evildoing behold the suffering [that awaits them, they will realize that] it will not be lightened for them [by virtue of their pleading]; and neither will they be granted 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 They will offer submission to God that Day, and the lies they fabricated will not be of the least avail. 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 [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
