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 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 On that Day they shall offer to submit to Allah, and what they forged will forsake them. 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 (bethink you of) the day when We raise in every nation a witness against them of their own folk, and We bring thee (Muhammad) as a witness against these. And We reveal the Scripture unto thee as an exposition of all things, and a guidance and a mercy and good tidings for those who have surrendered (to Allah). 89
