Musannaf Ibn Abi Shaybah 10023 — Fasting Shaban

Abu Salamah says: I asked Sayyidah Aishah (may Allah be pleased with her) about the fasting of the Messenger of Allah (peace and blessings be upon him), and she said: Sometimes the Prophet (peace and blessings be upon him) would fast continuously in a month in such a way that we felt he would not stop fasting, and sometimes he would stop fasting in such a way that we felt he would not fast. He fasted the most in the month of Sha'ban. He used to fast Sha'ban except for a little; rather, he used to fast the whole of Sha'ban.
