رَبَّنَا ظَلَمْنَا أَنْفُسَنَا وَإِنْ لَمْ تَغْفِرْ لَنَا وَتَرْحَمْنَا لَنَكُونَنَّ مِنَ الْخَاسِرِينَ

Rabbana dhalamna anfusana wa in lam taghfir lana wa tarhamna lanakoonanna minal-khaasireen

Our Lord, we have wronged ourselves, and if You do not forgive us and have mercy upon us, we will surely be among the losers.

Surah 7, Ayah 23 (7:23)
