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 they who were bent on evildoing behold the suffering [that awaits them, they will realize that] it will not be lightened for them [by virtue of their pleading]; and neither will they be granted 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 They will offer submission to God that Day, and the lies they fabricated will not be of the least avail. 87 For those who deny the truth and obstruct (others) from the way of God, We shall add torment to torment as they were perpetrating corruption. 88 And on that Day We shall raise up from every nation a witness from their own against them, and We shall bring you (Prophet Muhammad) as a witness against those. And We have sent down to you the Book making everything clear, as a guidance, and mercy, and glad tidings to those who submit. 89
