'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.  

أَنَّهُ حَدَّثَهُ قَالَ صَلَّيْتُ خَلْفَ النَّبِيِّ ﷺ وَأَبِي بَكْرٍ وَعُمَرَ وَعُثْمَانَ فَكَانُوا يَسْتَفْتِحُونَ بِ { الْحَمْدُ لِلَّهِ رَبِّ الْعَالَمِينَ} لاَ يَذْكُرُونَ بِسْمِ اللَّهِ الرَّحْمَنِ الرَّحِيمِ فِي أَوَّلِ قِرَاءَةٍ وَلاَ فِي آخِرِهَا  

[Machine] I prayed behind the Messenger of Allah ﷺ , Abu Bakr, Umar, and Uthman, and they would begin by reciting "Alhamdulillahi Rabbil 'Alamin" (Praise be to Allah, the Lord of all the worlds) [Surah Al-Fatiha: 2], without mentioning "Bismillahir Rahmanir Raheem" (In the name of Allah, the Most Gracious, the Most Merciful) [Surah Al-Fatiha: 1] in the beginning or at the end of the recitation.  

صَلَّيْتُ خَلْفَ رَسُولِ اللهِ ﷺ وَأَبِي بَكْرٍ وَعُمَرَ وَعُثْمَانَ فَكَانُوا يَسْتَفْتِحُونَ بِ {الْحَمْدُ لِلَّهِ رَبِّ الْعَالَمِينَ} [الفاتحة 2] لَا يَذْكُرُونَ {بِسْمِ اللهِ الرَّحْمَنِ الرَّحِيمِ} [الفاتحة 1] فِي أَوَّلِ الْقِرَاءَةِ وَلَا فِي آخِرِهَا
