Musannaf Ibn Abi Shayba 17:1229

Yazid ibn Harun narrated to us, he said: Hammad ibn Salamah informed us, from Asim, from Suwa', from Hafsah, that the Prophet, peace and blessings of Allah be upon him, when he would take to his bed, he would say: "My Lord, protect me from Your punishment on the day You resurrect Your servants."
