Sayyiduna Abu Ayyub Ansari (may Allah be pleased with him) says: Whenever I performed prayer behind the Messenger of Allah (peace and blessings be upon him), after completing the prayer I heard him recite this supplication:“O Allah! Forgive all my mistakes and sins. O Allah! Raise me, and mend my losses, and guide me to righteous deeds and good character. Indeed, none guides to their righteousness nor turns away their evil except You.”
