رَبَّنَا ظَلَمْنَا أَنْفُسَنَا وَإِنْ لَمْ تَغْفِرْ لَنَا وَتَرْحَمْنَا لَنَكُونَنَّ مِنَ الْخَاسِرِينَ

Rabbanā ẓalamnā anfusanā wa in lam taghfir lanā wa tarḥamnā lanakūnanna minal-khāsirīn

Our Lord, we have wronged ourselves. If You do not forgive us and show us mercy, we will certainly be among the losers.
