Sahih al-Bukhari 772
صحيح البخاري#772Sahihحَدَّثَنَا مُسَدَّدٌ، قَالَ حَدَّثَنَا إِسْمَاعِيلُ بْنُ إِبْرَاهِيمَ، قَالَ أَخْبَرَنَا ابْنُ جُرَيْجٍ، قَالَ أَخْبَرَنِي عَطَاءٌ، أَنَّهُ سَمِعَ أَبَا هُرَيْرَةَ ـ رضى الله عنه ـ يَقُولُ فِي كُلِّ صَلاَةٍ يُقْرَأُ، فَمَا أَسْمَعَنَا رَسُولُ اللَّهِ صلى الله عليه وسلم أَسْمَعْنَاكُمْ، وَمَا أَخْفَى عَنَّا أَخْفَيْنَا عَنْكُمْ، وَإِنْ لَمْ تَزِدْ عَلَى أُمِّ الْقُرْآنِ أَجْزَأَتْ، وَإِنْ زِدْتَ فَهُوَ خَيْرٌ.
Narrated Abu Huraira:The Qur'an is recited in every prayer and in those prayers in which Allah's Messenger (ﷺ) recited aloud for us, we recite aloud in the same prayers for you; and the prayers in which the Prophet (ﷺ) recited quietly, we recite quietly. If you recite "Al-Fatiha" only it is sufficient but if you recite something else in addition, it is better
Scholarly Authentication
The label above is the grade most of these scholars gave — one dissenting opinion no longer speaks for all of them. If any scholar calls a narration fabricated, that verdict is shown instead, whatever the others say. Each scholar's own wording:
Every narration in Sahih al-Bukhari is accepted as Sahih (authentic) by the established status of the book.
