Verse 12

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

If you could only see the guilty with their heads down in front of their Lord; our Lord, we have seen and we have heard, therefore, send us back and we will lead a righteous life, we have indeed attained certainty.
