رَبَّنَا ظَلَمْنَا أَنفُسَنَا وَإِن لَّمْ تَغْفِرْ لَنَا وَتَرْحَمْنَا لَنَكُونَنَّ مِنَ الْخَاسِرِينَ
Translation 
"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."
Note: This dua was made by Adam and Hawa (Eve) (may the peace and blessings of Allah be upon them) when they had eaten from the forbidden tree.
