It is narrated from Hazrat Anas (may Allah be pleased with him) that I had the honor of serving the Prophet (peace and blessings be upon him) for ten years, in travel and at home. It was not necessary that every action of mine would please the Prophet (peace and blessings be upon him), but the Prophet (peace and blessings be upon him) never even said "uff" to me. The Prophet (peace and blessings be upon him) never said to me, "Why did you do this?" or "Why did you not do this?"
