Huzaifa bin Yaman reported,

He prayed with the Prophet ﷺ, who would say in his bowing, "Glory be to my Lord, the Magnificent," and in his prostration, "Glory be to my Lord, the Most High." He did not pass a verse of mercy without pausing at it to ask, nor a verse of punishment without pausing at it to seek refuge.

عن حذيفة بن اليمان

أنه صلى مع النبي ﷺ فكان يقول في ركوعه: سبحان ربي العظيم وفي سجوده: سبحان ربي الأعلى وما مر بآية رحمة إلا وقف عندها، فسأل، ولا بآية عذاب إلا وقف عندها فتعوذ.
