English translation
890. It was narrated that Ibn Mas'ud said: "The Messenger of Allāh ﷺ said: 'When anyone of you bows, let him say in his bowing: 'Subhāna Rabbiyal-'Azim (Glory is to my Lord, the Most Great)" three times; if he does that his bowing will be complete. And when anyone of you prostrates, let him say in his prostration, 'Subhāna Rabbiyal-'A'la (Glory is to my Lord, the Most High)" three times; if he does that, his prostration will be complete, and that is the minimum.'" (Da'if)
