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 did wrong (the disbelievers) will see the torment, then it will not be lightened unto them, nor will they be given 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 And they will impart to Allah that Day [their] submission, and lost from them is what they used to invent. 87 For those who disbelieve and debar (men) from the way of Allah, We add doom to doom because they wrought corruption, 88 On the day when We call a witness against every nation from their own people, We will call you, (Muhammad), as a witness against them all. We have sent you the Book which clarifies all matters. It is a guide, a mercy, and glad news to the Muslims. 89
