Abu Musa Ashari reported,

The Prophet ﷺ used to make this supplication, "Allah, forgive me my sins, my ignorance, and my excess in my affairs, and whatever You know about me better than I know myself. Allah, forgive me my earnestness and my jesting, my mistakes and my deliberate wrongs, for all of that is found in me. Allah, forgive me what I have done before and what I will do later, what I have concealed and what I have made known, and whatever You know about me better than I know myself. You are the One who brings forward and You are the One who puts back, and You have power over all things."
