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 the evildoers behold the chastisement, it shall not be lightened for them, and no respite shall be given them. 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 And they proffer unto Allah submission on that day, and all that they used to invent hath failed them. 87 Those who disbelieve and bar others from the Path of Allah, We shall add punishment upon their punishment because they were corrupting. 88 And (remember) the Day when We shall raise up from every nation a witness against them from amongst themselves. And We shall bring you (O Muhammad SAW) as a witness against these. And We have sent down to you the Book (the Quran) as an exposition of everything, a guidance, a mercy, and glad tidings for those who have submitted themselves (to Allah as Muslims). 89
