Riyad-us-Saliheen 622
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 (PBUH), nor did I smell any fragrance more pleasant than the smell of Messenger of Allah (PBUH). 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]
This Hadith reflects the sublime morality of Messenger of Allah that he never found faults with the doings of his valet nor did he ever scold him during his ten-year-long service. To be sure, this is something unique in human history. May the Ummah, too, adopt the refined way of the living of its Prophet (PBUH).
