Sahih Muslim 2719 a
The Book Pertaining to the Remembrance of Allah, Supplication, Repentance and Seeking Forgiveness
Supplications [Of The Prophet (ﷺ)]
Abu Musa Ash'ari reported on the authority of his father that Allahs Messenger (ﷺ) used to supplicate in these words: " O Allah, forgive me my faults, my ignorance, my immoderation in my concerns. And You are better aware (of my affairs) than myself. O Allah, grant me forgiveness (of the faults which I committed) seriously or otherwise (and which I committed inadvertently and de- liberately. All these (failings) are in me. O Allah, grant me forgiveness from the fault which I did in haste or deferred, which I committed in privacy or in public and You are better aware of (them) than myself. You are the First and the Last and over all things You are Omnipotent."
