(13) باب كَانَ رَسُولُ اللَّهِ صلى الله عليه وسلم أَحْسَنَ النَّاسِ خُلُقًا
Anas b. Malik reported:
I served the Messenger of Allah (ﷺ) for ten years, and, by Allah, he never said to me any harsh word, and he never said to me about a thing as to why I had done that and as to why I had not done that. Abu Rabi' has made this addition (in this narration):" The work which a servant should do." There is no mention of his words" By Allah".
