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 the unjust will see the punishment, from that time on it will not be lightened for them, nor will they get 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 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 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
