Musannaf Ibn Abi Shayba 3:5946

Ubayd Allah ibn Musa narrated to us, Shayban informed us, from Yahya ibn Abi Kathir, from Abu Salamah, from Abdullah ibn Amr ibn al-Aas, that when the sun eclipsed during the time of the Messenger of Allah (may Allah bless him and grant him peace), it was called out for prayer: "The prayer is gathering." The Messenger of Allah (may Allah bless him and grant him peace) bowed two bowings in one prostration, then he stood and bowed two bowings in one prostration, then the sun cleared. She (Aisha) said: "I have never prostrated a prostration, nor have I bowed a bowing, that was longer than it."
