صحيح البخاري#4705Sahihحَدَّثَنِي يَعْقُوبُ بْنُ إِبْرَاهِيمَ، حَدَّثَنَا هُشَيْمٌ، أَخْبَرَنَا أَبُو بِشْرٍ، عَنْ سَعِيدِ بْنِ جُبَيْرٍ، عَنِ ابْنِ عَبَّاسٍ، رضى الله عنهما {الَّذِينَ جَعَلُوا الْقُرْآنَ عِضِينَ} قَالَ هُمْ أَهْلُ الْكِتَابِ، جَزَّءُوهُ أَجْزَاءً، فَآمَنُوا بِبَعْضِهِ وَكَفَرُوا بِبَعْضِهِ.
Narrated Ibn `Abbas:Those who have made their Scripture into parts are the people of the Scripture who divided it into portions and believed in a part of it and disbelieved the other
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.
