Abu Dawood: Hadith 1181

There was an eclipse of the sun during the lifetime of the Messenger of Allah (ﷺ)came tot he mosque; he stood up and uttered the takbir (Allah is great); the people stood in rows behind him; the Messenger of Allah (ﷺ) recited from the Quran for a long time; then he uttered the takbir (Allah is most great) and performed bowing for a long time, then he raised his head and said: Allah listens to him who praises Him; our Lord, and to You be praise; then he stood up and recited from the Qur'an for a long time, but it was less than the first (recitation); he then bowed for a long time, but it was less than the first bowing; he then said, Allah listens to him who praises Him; our Lord, and to You be praise. he then did so in the second rak'ah. he thus completed four bowings and four prostrations. The sun had become bright before he departed.
