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 have done wrong will behold the torment, it will not be lightened unto them, nor will they 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 For those who disbelieve and debar (men) from the way of Allah, We add doom to doom because they wrought corruption, 88 And (bethink you of) the day when We raise in every nation a witness against them of their own folk, and We bring thee (Muhammad) as a witness against these. And We reveal the Scripture unto thee as an exposition of all things, and a guidance and a mercy and good tidings for those who have surrendered (to Allah). 89
