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, so that I could present water for ablution. I used to hear that whenever the Prophet, peace and blessings be upon him, woke up for prayer, he would keep saying“Alhamdulillahi Rabbil ‘Alamin”for a long time, then he would keep saying“Subhanallahi Al-‘Azim wa bihamdih”for a long time.
