أَخْبَرَنَا عَبْدُ اللَّهِ بْنُ سَعِيدٍ أَبُو سَعِيدٍ الأَشَجُّ، قَالَ حَدَّثَنِي عُقْبَةُ بْنُ خَالِدٍ، قَالَ حَدَّثَنَا شُعْبَةُ، وَابْنُ أَبِي عَرُوبَةَ، عَنْ قَتَادَةَ، عَنْ أَنَسٍ، قَالَ صَلَّيْتُ خَلْفَ رَسُولِ اللَّهِ صلى الله عليه وسلم وَأَبِي بَكْرٍ وَعُمَرَ وَعُثْمَانَ - رضى الله عنهم - فَلَمْ أَسْمَعْ أَحَدًا مِنْهُمْ يَجْهَرُ بِـ { بِسْمِ اللَّهِ الرَّحْمَنِ الرَّحِيمِ } .
It was narrated that Anas said: "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."
