صحيح البخاري#650Sahihحَدَّثَنَا عُمَرُ بْنُ حَفْصٍ، قَالَ حَدَّثَنَا أَبِي قَالَ، حَدَّثَنَا الأَعْمَشُ، قَالَ سَمِعْتُ سَالِمًا، قَالَ سَمِعْتُ أُمَّ الدَّرْدَاءِ، تَقُولُ دَخَلَ عَلَىَّ أَبُو الدَّرْدَاءِ وَهْوَ مُغْضَبٌ فَقُلْتُ مَا أَغْضَبَكَ فَقَالَ وَاللَّهِ مَا أَعْرِفُ مِنْ أُمَّةِ مُحَمَّدٍ صلى الله عليه وسلم شَيْئًا إِلاَّ أَنَّهُمْ يُصَلُّونَ جَمِيعًا.
Narrated Salim:I heard Um Ad-Darda' saying, "Abu Ad-Darda' entered the house in an angry mood. I said to him. 'What makes you angry?' He replied, 'By Allah! I do not find the followers of Muhammad doing those good things (which they used to do before) except the offering of congregational prayer." (This happened in the last days of Abu Ad-Darda' during the rule of `Uthman)
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.
