Mishkat al-Masabih 1218 — The Prophet’s ﷺ night prayer

Rabi'a b. Ka‘b al-Aslami said he used to spend the night near the Prophet’s inner chamber and hear him say when he got up during the night, “Glory be to the Lord of the universe" for a long time. Then he would say, “Glory be to God and praise be to Him" for a longtime. Nasa’i transmitted it, and Tirmidhi who has something similar says that this is a hasan sahih tradition.
