Sunan an-Nasa'i

It was narrated that Abdullah bin 'Amr said: "The sun was eclipsed during the time of the Messenger of Allah (ﷺ), so he issued orders that the call be given: “As-salatu jam'iah. The Messenger of Allah (ﷺ) led the people in prayer, bowing twice and prostrating twice. Then he stood and prayed, bowing twice and prostrating once. 'Aishah said: “I never bowed or prostrated for so long as that””"
