صحيح البخاري#85Sahihحَدَّثَنَا الْمَكِّيُّ بْنُ إِبْرَاهِيمَ، قَالَ أَخْبَرَنَا حَنْظَلَةُ بْنُ أَبِي سُفْيَانَ، عَنْ سَالِمٍ، قَالَ سَمِعْتُ أَبَا هُرَيْرَةَ، عَنِ النَّبِيِّ صلى الله عليه وسلم قَالَ " يُقْبَضُ الْعِلْمُ، وَيَظْهَرُ الْجَهْلُ وَالْفِتَنُ، وَيَكْثُرُ الْهَرْجُ ". قِيلَ يَا رَسُولَ اللَّهِ وَمَا الْهَرْجُ فَقَالَ هَكَذَا بِيَدِهِ، فَحَرَّفَهَا، كَأَنَّهُ يُرِيدُ الْقَتْلَ.
Narrated Abu Huraira:The Prophet (ﷺ) said, "(Religious) knowledge will be taken away (by the death of religious scholars) ignorance (in religion) and afflictions will appear; and Harj will increase." It was asked, "What is Harj, O Allah's Messenger (ﷺ)?" He replied by beckoning with his hand indicating "killing." (Fath-al-Bari Page 192, Vol)
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.
