Musannaf Ibn Abi Shayba 35:448

Hushaym narrated to us, Yunus informed us, from al-Hasan, from Abu Burdah, who said: The sun eclipsed during the time of the Messenger of Allah (may Allah bless him and grant him peace), so he said: "Indeed, the sun and the moon are two signs from among the signs of Allah. They do not eclipse for the death of anyone among the people. So when that happens, pray until it clears."
