It is narrated from Sayyiduna Rabi’ah bin Ka’b (may Allah be pleased with him) that I used to sleep in the blessed chamber of the Prophet (peace and blessings be upon him). I used to hear that whenever the Prophet (peace and blessings be upon him) woke up for prayer, he would say“Alhamdulillahi Rabbil ‘Alamin”for a long time, then he would say“Subhanallahi Al-‘Azim wa bihamdihi”for a long time.
