Muslim 6901
The Book Pertaining to the Remembrance of Allah, Supplication, Repentance and Seeking Forgiveness
Abu Musa Ash'ari reported on the authority of his father that Allahs Apostle (ﷺ) used to supplicate in these words:" O Allah, forgive me my faults, my ignorance, my immoderation in my concerns. And Thou art 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 Thou art better aware of (them) than myself. Thou art the First and the Last and over all things Thou art Omnipotent
