Where refuge is sought four times over
ʿUmar recited it loudly enough that people learned it from him.
سُبْحَانَكَ اللَّهُمَّ وَبِحَمْدِكَ تَبَارَكَ اسْمُكَ وَتَعَالَى جَدُّكَ وَلاَ إِلَهَ غَيْرُكَ
Subḥānaka-llāhumma wa bi-ḥamdik, wa tabāraka-smuk, wa taʿālā jadduk, wa lā ilāha ghayruk.
“Glory be to You, O Allah, and praise. Blessed is Your name, exalted is Your majesty, and there is no god but You.”
The full narration
Abda reported:'Umar b. al-Khattab used to recite loudly these words: Subhanak Allahumma wa bi hamdika wa tabarakasmuka wa ta'ala jadduka wa la ilaha ghairuka [Glory to Thee,0 Allah, and Thine is the Praise, and Blessed is Thy Name. and Exalted is Thy Majesty. and there is no other object of worship beside Thee]. Qatada informed in writing that Anas b. Malik had narrated to him: I observed prayer behind the Messenger of Allah (ﷺ) and Abu Bakr and Umar and 'Uthman. They started (loud recitation) with: AI-hamdu lillahi Rabb al-'Alamin [All Praise is due to Allah, the Lord of the worlds] and did not recite Bismillah ir- Rahman-ir-Rahim (loudly) at the beginning of the recitation or at the end of it
