Sayyiduna Anas bin Malik (may Allah be pleased with him) narrates: Three men came to the houses of the wives of the Prophet (peace and blessings be upon him) in order to ask about the worship of the Prophet (peace and blessings be upon him). When they were informed about it, they considered it little. They said: What connection do we have with the Prophet (peace and blessings be upon him)? The Prophet (peace and blessings be upon him) has had his past and future sins forgiven. So one of them said: I will always offer voluntary prayers throughout the night. The second said: I will always observe voluntary fasts and never break my fast. The third said: I will keep away from women and never marry. The Prophet (peace and blessings be upon him) came and these things were told to him. He said: Did you say these things? By Allah! I am the one among you who fears Allah the most and has the most taqwa. But I observe voluntary fasts and also leave them; I offer voluntary prayers and also sleep; and I have also married women. So whoever turns away from my Sunnah has nothing to do with me.
