Sahih Muslim: Hadith 1085

I asked 'Ata': What do you recite when you are in a state of bowing (in prayer)? He said:" Hallowed be You, and with Your praise, there is no god but You." Son of Abd Mulaika narrated to me on the anthority of 'A'isha (who reported): I missed one night the Messenger of Allah (ﷺ) (from his bed). I thought that he might have gone to one of his other wives. I searched for him and then came back and (found him) in a state of bowing, or prostration, saying: Hallowed be You and with Your praise; there is no god but You. I said: With my father mayest you be ransomed and with my mother. I was thinking of (another) affair, whereas you are (occupied) in another one.
