Musannaf Ibn Abi Shayba 3:5933

8310. Ibn Numayr narrated to us, from Hisham, from Fatimah, from Asma, who said: The sun eclipsed during the time of the Messenger of Allah, may Allah bless him and grant him peace. The Messenger of Allah, may Allah bless him and grant him peace, prolonged [the prayer] until I was overcome by fainting. She said: Then the Messenger of Allah, may Allah bless him and grant him peace, turned away, and it [the sun] had cleared.
