Anas (May Allah be pleased with him) reported:
I never felt any piece of velvet or silk softer than the palm of the Messenger of Allah (ﷺ), nor did I smell any fragrance more pleasant than the smell of Messenger of Allah (ﷺ). I served him for ten years, and he never said 'Uff' (an expression of disgust) to me. He never said 'why did you do that?' for something I had done, nor did he ever say 'why did you not do such and such' for something I had not done.[Al- Bukhari and Muslim].
