Sunan Ibn Majah 3879

Rabi’ah bin Ka’b Al-Aslami narrated that he used to spend the night outside the door of the Messenger of Allah (ﷺ), and he used to hear the Messenger of Allah (ﷺ) saying at night:“Subhan Allahi Rabbil-‘alamin (Glory is to Allah, the Lord of the worlds),” repeating that for a while, then he said: Subhan Allahi wa bihamdihi (Glory and praise is to Allah).”
