"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.)" (Using translation from Nasāʾī 900)
أَنَّ رَسُولَ اللهِ ﷺ كَانَ إِذَا اسْتَفْتَحَ الصَّلَاةَ قَالَ «سُبْحَانَكَ اللهُمَّ وَبِحَمْدِكَ وَتَبَارَكَ اسْمُكَ وَتَعَالَى جَدُّكَ وَلَا إِلَهَ غَيْرُكَ»
