Ahmad ibn 'Abdullah ibn Yunus narrated to us, Zuhayr narrated to us, Yahya ibn Sa'id narrated to us, from Abu Salama, who said: I heard 'A'ishah, may Allah be pleased with her, say: "I would have fasts due upon me from Ramadan, and I would not be able to make them up except in Sha'ban, due to my occupation with the Messenger of Allah, peace and blessings be upon him, or because of the Messenger of Allah, peace and blessings be upon him."
