Anas bin Malik (RA) 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".
