It is narrated from Sayyiduna Hudhayfah bin Yaman (may Allah be pleased with him) that he came to the Noble Prophet (peace and blessings be upon him) and said: I was leading the prayer when, in the middle of the prayer, I heard a man reciting this supplication: "O Allah! All praise is for You, all sovereignty is for You, all goodness is in Your hand, all matters are returned to You, whether open or hidden. You are worthy of being praised. Indeed, You have power over all things. O Allah! Forgive me all the sins I have committed, protect me in the remaining part of my life, and grant me pure deeds by which You will be pleased with me." The Noble Prophet (peace and blessings be upon him) said regarding this supplication and voice: This was an angel who came to teach you how to praise your Lord.
