Musannaf Ibn Abi Shayba 3:5934

Ibn Fudayl narrated to us, from Yazid, from Abd al-Rahman ibn Abi Layla, who said: So-and-so and so-and-so narrated to me that the Prophet, peace and blessings of Allah be upon him, said: "Indeed, the eclipse of the sun and the moon are two signs from the signs of Allah. So when you see that, then hasten to the prayer."
