[Machine] I heard the Prophet ﷺ making a supplication for opening except that I heard him say, "He starts with the saying Subhan Rabbiyal A’la Waahib (Glory be to my Lord, the Most High, the Bestower)."
سَمِعْتُ النَّبِيَّ ﷺ يَسْتَفْتِحُ بِدُعَاءٍ إِلَّا سَمِعْتُهُ «يَسْتَفْتِحُ بِسُبْحَانَ رَبِّيَ الْأَعْلَى الْوَهَّابِ»
