Mukhtasar Bukhari

Narrated from Abu Hurairah (may Allah be pleased with him), he says: I heard the Messenger of Allah (peace and blessings of Allah be upon him) say: "When a servant reaches a sin," and at times he said: "When he commits a sin and says: O Lord! I have sinned," and at times he said (he says): "I have reached a sin," then Allah Almighty says: My servant knows that (there is) his Lord who forgives his sins and takes him to account (from whose fear he seeks refuge). I have forgiven My servant. Then (after a short while) the servant again reaches a sin or commits a sin and says: O Lord! I have sinned or I have reached a sin, so forgive me. Allah Almighty says: My servant knows that his Lord is the One who forgives sins and also takes to account. I have forgiven My servant. Then (after a short while) he again commits a sin or said: "reaches a sin" and says: O Lord! I have reached a sin or I have committed a sin, so forgive me. Allah Almighty says: My servant knows that surely his Lord is the One who forgives sins and takes to account. I have forgiven My servant, so let him do what he wishes." (The Messenger of Allah, peace and blessings be upon him, said this) three times.
