As-Sajdah - 32:12

وَلَوْ تَرَى إِذِ الْمُجْرِمُونَ نَاكِسُو رُؤُوسِهِمْ عِندَ رَبِّهِمْ رَبَّنَا أَبْصَرْنَا وَسَمِعْنَا فَارْجِعْنَا نَعْمَلْ صَالِحًا إِنَّا مُوقِنُونَ
[32:12]
And could you but see when the guilty shall hang down their heads before their Lord: Our Lord! we have seen and we have heard, therefore send us back, we will do good; surely (now) we are certain.
If only thou couldst see when the guilty ones will bend low their heads before their Lord, (saying:) "Our Lord! We have seen and we have heard: Now then send us back (to the world): we will work righteousness: for we do indeed (now) believe."
Couldst thou but see when the guilty hang their heads before their Lord, (and say): Our Lord! We have now seen and heard, so send us back; we will do right, now we are sure.
