Sunan Abi Dawud 1179

Narrated Jabir: There was an eclipse of the sun in the time of the Messenger of Allah (ﷺ) on a hot day. The Messenger of Allah (ﷺ)led his Companions in prayer and prolonged the standing until the people began to fall down. He then bowed and prolonged it; then he raised his head and prolonged (the stay); then he bowed and prolonged it; then he raised his head and prolonged (the stay); then he made two prostrations and then stood up; then he did in the same manner. He thus performed four bowings and four prostrations. Then the narrator narrated the rest of the tradition.
