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, both during travel and at home. It was not necessary that everything I did was pleasing to 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?"
