question #2 Sahih al-Bukhari 6038, Book 78, Hadith 68 : What can be learned about the Prophet’s (ﷺ) character from his treatment of his servant over a decade?

I served the Prophet (ﷺ) for ten years, and he never said to me, “Uf” (a minor harsh word denoting
impatience) and never blamed me by saying, “Why did you do so or why didn’t you do so?”
