Sunan An-Nasa'i

It was narrated from Abu Sa'eed that:When the Prophet (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)
