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 harmdoers see their punishment, it shall never be lightened, nor shall they ever be respited. 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 (As for) those who disbelieve and turn away from Allah's way, We will add chastisement to their chastisement because they made mischief. 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
