Sura al-Sajdah 32:12

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

wa-law tara idhi l-mujrimūna nākisū ruʾūsihim ʿinda rabbihim rabbanā abṣarnā wa-samiʿnā fa-irjiʿnā naʿmal ṣāliḥan innā mūqinūna

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."
