Rabia bin Kaab reported,

Ubayy reported, "I used to spend the night near the door of the Prophet ﷺ and would bring him his water for ablution. I would hear him for long stretches of the night saying, 'Allah hears whoever praises Him,' and I would hear him for long stretches of the night reciting, 'Praise be to Allah, Lord of the worlds' [Fatihah 1:2]."
