Sunan an-Nasai
أَخْبَرَنَا عُبَيْدُ اللَّهِ بْنُ فَضَالَةَ بْنِ إِبْرَاهِيمَ، قَالَ أَنْبَأَنَا عَبْدُ الرَّزَّاقِ، قَالَ أَنْبَأَنَا جَعْفَرُ بْنُ سُلَيْمَانَ، عَنْ عَلِيِّ بْنِ عَلِيٍّ، عَنْ أَبِي الْمُتَوَكِّلِ، عَنْ أَبِي سَعِيدٍ، أَنَّ النَّبِيَّ صلى الله عليه وسلم كَانَ إِذَا افْتَتَحَ الصَّلاَةَ قَالَ " سُبْحَانَكَ اللَّهُمَّ وَبِحَمْدِكَ تَبَارَكَ اسْمُكَ وَتَعَالَى جَدُّكَ وَلاَ إِلَهَ غَيْرُكَ " .
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.)"
