(4) باب النَّهْىِ عَنِ التَّبَتُّلِ، .
Narrated Anas:
It was narrated from Anas that there was a group of the Companions of the Prophet, one of whom said: "I will not marry women." Another said: "I will not eat meat." Another said: "I will not sleep on a bed." Another said: "I will fast and not break my fast." News of that reached the Messenger of Allah and he praised Allah then said: "What is the matter with people who say such and such? But I pray and I sleep, I fast and I break my fast, and I marry women. Whoever turns away from my Sunnah is not of me."
