Musannaf Ibn Abi Shayba 3:2361

Al-Fadl ibn Dukayn narrated to us, from Abd al-Jabbar, from Abbas, from Awn ibn Abi Juhayfah, from his father, who said: The Messenger of Allah (ﷺ) was on a journey during which they slept until the sun rose. Then he said: "Indeed, you were dead, and Allah returned your souls to you. So whoever sleeps through a prayer or forgets a prayer, let him pray it when he remembers it and when he wakes up."
