But one Day We shall raise up a witness out of every community, whereupon they who were bent on denying the truth will not be allowed to plead [ignorance,] and neither will they be allowed to make amends. 84 And when those who did wrong behold the doom, it will not be made light for them, nor will they be reprieved. 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 on that Day will they [who had thus been sinning, belatedly] proffer their surrender to God; and all their false imagery will have forsaken them. 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 Remind them of the Day when We shall call from every people a witness against them, and make you a witness over them, for We have revealed to you the Book as an exposition of everything, and as guidance and grace and happy tidings for those who submit. 89
