Sunan an-Nasa'i, Volume 2, Book 16, Hadith 1484 (DarusSalam) ⓘ
It was narrated that Abu Hurairah said: "The sun eclipsed during the time of the Messenger of Allah. He stood and led the people in prayer. He stood for a long time, then he bowed for a long time, then he stood for a long time that was shorter than the first time, then he bowed for a long time that was shorter than the first time. Then he prostrated for a long time, then he sat up, then he prostrated for a long time that was shorter than the first time. Then he stood up and bowed twice again, doing the same again. Then he prostrated twice, doing the same again, until he had finished his prayer. Then he said: 'The sun and the moon are two of the signs of Allah (SWT), and they do not become eclipsed for the death or birth of anyone. If you see that then hasted to remember Allah (SWT) and pray.'"
