Chapter 70: The fast of the Prophet, Book 22: The Book of Fasting
Grade: Sahih (Darussalam)
Yahya related to me from Malik from Abu'n Nadr, the mawla of Umar ibn Ubaydullah, from Abu Salama ibn Abd ar-Rahman that A'isha, the wife of the Prophet, may Allah bless him and grant him peace, said, "The Messenger of Allah, may Allah bless him and grant him peace, used to fast for so long that we thought he would never stop fasting, and he would go without fasting for so long that we thought he would never fast again. I never saw the Messenger of Allah, may Allah bless him and grant him peace, fast for a complete month except for Ramadan, and I never saw him do more fasting in any one month than he did in Shaban.'
Yahya related to me from Malik from Yahya ibn Said from Abu Salama ibn Abd ar-Rahman that he heard A'isha, the wife of the Prophet, may Allah bless him and grant him peace, say, "I used to have to make up days from Ramadan and not be able to do them until Shaban came."
It was narrated that Simak said: "I entered upon 'Ikrimah on the day concerning which there was doubt as to whether it was Ramadan or Shaban, and he was eating bread, vegetables and milk. He said: 'Come and eat.' I said: 'I am fasting.' He adjured me by Allah to break my fast. I said Subhan-Allah twice. When I saw that he was insisting, I went forward and said: 'Give me what you have.' He said: 'I heard Ibn 'Abbas say: The Messenger of Allah said: 'Fast when you see it (the crescent) and stop fasting when you see it, and if clouds or darkness prevent you from seeing it, then complete the number of days of Shaban, and do not fast ahead of the month, and do not join Ramadan to a day of Shaban." '

It was narrated that Abu Salamah said: "I asked Aishah: 'Tell me about the fasting of the Messenger of Allah.' She said: 'he used to fast until we said: he is going to fast until we said: He is not going to fast. He never fasted any month more than Shaban. He used to fast (all) of Shaban except a little, he used to fast all of Shaban."' '
