Musannaf Ibn Abi Shayba 21:181

Ghundar narrated to us, from Shu'bah, from 'Abdullah ibn Abi al-Safar, who said: I heard Abu Bakr ibn Abi Musa narrating from al-Bara' that the Prophet, peace and blessings of Allah be upon him, when he would wake up, he would say: "Praise be to Allah who gave us life after He caused us to die, and to Him is the resurrection." Shu'bah said: This or the like of it. And when he would sleep, he would say: "O Allah, in Your name I live and in Your name I die."
