It was narrated that Rabi’ah bin Ka’b Al-Aslami said: “I used to stay overnight at the Prophet’s (ﷺ) apartment and I used to hear him when he prayed Qiyam at night saying: ‘Subhan Allahi Rabil-Alamin (Glory be to Allah, the Lord of the worlds)’ for a long time, then he said: ‘Subhan Allah wa bi hamdih (Glory and praise be to Allah) for a long time.”
