It was narrated that Abu Sa'eed said:
When the Messenger of Allah (ﷺ) started to pray, he would say: 'Subhanakallahumma, wa bihamdika tabarakasmuka wa ta'ala jadduka wa la ilaha ghairuk (Glory and praise be to You, O Allah. Blessed be Your name and exalted be Your majesty, there is none worthy of worship except You.)
