The du’a of Adam (as)

رَبَّنَا ظَلَمْنَا أَنفُسَنَا وَإِن لَّمْ تَغْفِرْ لَنَا وَتَرْحَمْنَا لَنَكُونَنَّ مِنَ الْخَاسِرِينَ

Rabbana zalamna anfusana, wa il-lam taghfir lana wa tarhamna, lanakunanna minal-khasirin.

“Our Lord, we have wronged ourselves. If You do not forgive us and have mercy on us, we will surely be among the losers.”
