It is narrated from Hazrat Hudhaifa (may Allah be pleased with him) that once he presented himself before the Prophet Muhammad (peace and blessings be upon him) and said: I was performing prayer when suddenly I heard a man saying: O Allah! All praise is for You, all sovereignty is for You, all kinds of goodness are in Your hand, all matters return to You, whether apparent or hidden. You alone are worthy of being praised. Surely, You have power over all things. O Allah! Forgive all the sins that I have committed, and in whatever part of life remains, protect me from sins, and grant me the ability to perform such righteous deeds with which You become pleased. The Prophet Muhammad (peace and blessings be upon him) said: That was an angel who came to teach you the praise of your Lord.
