﴿ وَلَوْ تَرَىٰٓ إِذِ ٱلْمُجْرِمُونَ نَاكِسُوا۟ رُءُوسِهِمْ عِندَ رَبِّهِمْ رَبَّنَآ أَبْصَرْنَا وَسَمِعْنَا فَٱرْجِعْنَا نَعْمَلْ صَٰلِحًا إِنَّا مُوقِنُونَ ﴾

“If thou couldst but see [how it will be on Judgment Day], when those who are lost in sin will hang their heads before their Sustainer, [saying:] “O our Sustainer! [Now] we have seen, and we have heard! Return us, then, [to our earthly life] that we may do good deeds: for [now], behold, we are certain [of the truth]!””
