Opening supplication (istiftah)

سُبْحَانَكَ اللَّهُمَّ وَبِحَمْدِكَ، وَتَبَارَكَ اسْمُكَ، وَتَعَالَى جَدُّكَ، وَلاَ إِلَهَ غَيْرُكَ

Subhanakallahumma wa bihamdika, wa tabarakasmuka, wa ta'ala jadduka, wa la ilaha ghayruk

“Glory is to You, O Allah, and praise; blessed is Your name and exalted is Your majesty; there is no god but You.”

— Sunan Abi Dawud 775 (sahih)
