Sayyiduna Anas (may Allah be pleased with him) said: Three men came to the wives of the Prophet (peace and blessings be upon him) asking about the worship of the Prophet (peace and blessings be upon him). When they were told about it, it was as if they considered it little, and they said: Where are we compared to the Prophet (peace and blessings be upon him), when Allah Almighty has forgiven his past and future sins? One of them said: As for me, I will always pray all night. Another said: I will fast continuously and never break my fast. The third said: I will keep away from women and never marry. Then the Prophet (peace and blessings be upon him) came to them and said: "Are you the ones who said such and such? Indeed, I fear Allah the most among you and am the most mindful of Him, yet I fast and I break my fast, I pray and I sleep, and I marry women. So whoever turns away from my Sunnah is not of me."
