It is narrated from Sayyiduna Abu Musa (may Allah be pleased with him) that the Noble Prophet (peace and blessings be upon him) used to supplicate: "O Allah! Forgive me my sins, my ignorance, my excesses in my affairs, and whatever You know better about me than I do. O Allah! Forgive me my seriousness and my jest, my mistakes and my deliberate actions, and all of that is within me." (O Allah! Forgive my sins which I committed out of ignorance, those I committed by exceeding the limits, and those sins which You know better than I do. O Allah! Forgive those sins which I committed seriously, those I committed in jest, those I committed unintentionally, and those I committed out of ignorance, and all these sins are within me.)
