رَبَّنَا ظَلَمْنَا أَنفُسَنَا وَإِن لَّمْ تَغْفِرْ لَنَا وَتَرْحَمْنَا لَنَكُونَنَّ مِنَ الْخَاسِرِينَ
Transliteration
Rabbana zalamna anfusana, wa in lam taghfir lana wa tarhamna lanakunanna min al-khasirin.
Translation
"Our Lord, we have wronged ourselves. If You do not forgive us and have mercy on us, we will surely be among the losers."
Surah Al-A'raf 7:23
