Ibn Umm Maktum · The Book of Fasting

""I asked 'Aishah about the fasting of the Messenger of Allah. She said: 'The Messenger of Allah used to fast until we said that he is going to fast (continually), and he used not to fast until we said: he is not going to fast. And he did not fast for a whole month from the time he came to Al-Madinah, apart from Ramadan."' '
