General Behavior (Kitab Al-Adab) hadith Sunan Abu-Dawud

Narrated Anas ibn Malik: I served the Prophet (peace_be_upon_him) at Medina for ten years. I was a boy. Every work that I did was not according to the desire of my master, but he never said to me: Fie, nor did he say to me: Why did you do this? or Why did you not do this?
