Musannaf Ibn Abi Shayba 3:5931

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