quran:32:12 –

If you could but see when the criminals are hanging their heads before their Lord, ˹saying˺, "Our Lord, we have seen and heard, so return us ˹to the world˺; we will work righteousness. Indeed, we are ˹now˺ certain."  

And if could you but see the guilty, the disbelievers, hanging their heads ˹low˺ before their Lord, lowering them in shame, saying: ‘Our Lord! We have seen, the resurrection that we denied, and heard, from You the confirmation of ˹the truth of˺ the messengers concerning that in which we used to call them liars. So send us back, to the world, so that we may act righteously, therein, for indeed we are convinced’, now. But none of this is of any use to them and they will not be sent back (the response to ˹the conditional clause beginning with˺ law, ‘if’, is ˹an implicit˺ ‘you would see a terrible thing’).
