Narrated Anas bin Malik: A group of three men came to the houses of the wives of the Prophet (peace be upon him) asking how the Prophet (peace be upon him) worshipped (Allah), and when they were informed about that, they considered their worship insufficient and said, “Where are we from the Prophet (peace be upon him) as his past and future sins have been forgiven.” Then one of them said, “I will offer the prayer throughout the night forever.” The other said, “I will fast throughout the year and will not break my fast.” The third said, “I will keep away from the women and will not marry forever.” Allah’s Apostle came to them and said, “Are you the same people who said so-and-so? By Allah, I am more submissive to Allah and more afraid of Him than you; yet I fast and break my fast, I do sleep and I also marry women. So he who does not follow my tradition in religion, is not from me (not one of my followers).”
Sahih Al-Bukhari – Book 62 Hadith 1
Narrated Aisha and Umm Salamah: The Messenger of Allah (peace be upon him) at times got up in the morning in a state of Junub on account of having a sexual intercourse (with his wives during night) but not due to sexual dreams in the month of Ramadan, and would observe fast.
Sahih Al-Bukhari – Book 62 Hadith 3
Narrated Salamah ibn Sakhr al-Bayadi I was a man who was more given than others to sexual intercourse with women. When the month of Ramadan came, I feared lest I should have intercourse with my wife, and this evil should remain with me till the morning. So I made my wife like my mother’s back to me till the end of Ramadan. But one night when she was waiting upon me, something of her was revealed. Suddenly I jumped upon her. When the morning came I went to my people and informed them about this matter. I said: Go along with me to the Apostle of Allah (peace be upon him). They said: No, by Allah. So I went to the Prophet (peace be upon him) and informed him of the matter. He said: Have you really committed it, Salamah? I said: I committed it twice, Apostle of Allah. I am content with the Commandment of Allah, the Exalted; so take a decision about me according to what Allah has shown you. He said: Free a slave. I said: By Him Who sent you with truth, I do not possess a neck other than this: and I struck the surface of my neck. He said: Then fast two consecutive months. I said: Whatever I suffered is due to fasting. He said: Feed sixty poor people with a wasq of dates. I said: By Him Who sent you with truth, we passed the night hungry; there was no food in our house. He said: Then go to the collector of sadaqah of BanuZurayq; he must give it to you. Then feed sixty poor people with a wasq of dates; and you and your family eat the remaining dates. Then I came back to my people, and said (to them): I found with you poverty and bad opinion; and I found with the Prophet (peace be upon him) prosperity and good opinion. He has commanded me to give alms to you. Ibn al-Ala’ added: IbnIdris said: Bayadah is a sub-clan of BanuZurayq.
