"I prayed behind the Messenger of Allah ﷺ, Abu Bakr, Umar and Uthman, may Allah be pleased with them, and I did not hear any of them say out loud: In the Name of Allah, The Most Gracious, The Most Merciful." (Using translation from Nasāʾī 907)
«صَلَّيْتُ خَلْفَ رَسُولِ اللهِ ﷺ وَأَبِي بَكْرٍ وَعُمَرَ وَعُثْمَانَ فَلَمْ أَسْمَعْ أَحَدًا مِنْهُمْ يَجْهَرُ بِبِسْمِ اللهِ الرَّحْمَنِ الرَّحِيمِ»
