It was narrated that Ab Salamah said: “I asked Aishah (RA) : ‘Tell me about the fasting of the Messenger of Allah ﷺ She said: ‘He used to fast until we said: He is going to fast (continually), and he used not to fast until we said: He is not going to fast. He never fasted any month more than Sha’ban. He used to fast (all) of Sha’bán except a little, he used to fast all of Sha’ban.” (Sahih).
