Hazrat Aisha (may Allah be pleased with her) narrates: One night I searched for the Messenger of Allah (peace and blessings be upon him) but did not find him. Hazrat Aisha (may Allah be pleased with her) says: I thought perhaps he had gone to one of his slave girls or wives. Then I found him in the state of prostration, and he was reciting this supplication: O Allah! Forgive me for those deeds which I have done secretly or openly.
