It is narrated from Hazrat Aisha (may Allah be pleased with her) that the Prophet (peace and blessings be upon him) used to frequently say in his bowing and prostration: "Subhanaka Rabbana wa bihamdika Allahumma ighfir li" (Glory is to You, our Lord, and with Your praise. O Allah, forgive me), and he used to act upon the Noble Qur'an.
