I served the Prophet ﷺ for ten years, and by Allah, he never once said "uff" to me, nor did he ever say about something I had done, "Why did you do this?" or about something I had not done, "Why did you not do this?"
حدثنا يونس حدثنا حماد يعني ابن زيد عن ثابت
خدمت النبي ﷺ عشر سنين فوالله ما قال لي أف قط ولا قال لشيء صنعته لم صنعت كذا وهلا صنعت كذا وكذا
