Surah As-Sajdah Verse-12

وَلَوْ تَرَى إِذِ الْمُجْرِمُونَ نَاكِسُو رُؤُوسِهِمْ عِندَ رَبِّهِمْ رَبَّنَا أَبْصَرْنَا وَسَمِعْنَا فَارْجِعْنَا نَعْمَلْ صَالِحًا إِنَّا مُوقِنُونَ
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."
