Sahih al-Bukhari 7143
صحيح البخاري#7143Sahihحَدَّثَنَا سُلَيْمَانُ بْنُ حَرْبٍ، حَدَّثَنَا حَمَّادٌ، عَنِ الْجَعْدِ، عَنْ أَبِي رَجَاءٍ، عَنِ ابْنِ عَبَّاسٍ، يَرْوِيهِ قَالَ قَالَ النَّبِيُّ صلى الله عليه وسلم " مَنْ رَأَى مِنْ أَمِيرِهِ شَيْئًا فَكَرِهَهُ فَلْيَصْبِرْ، فَإِنَّهُ لَيْسَ أَحَدٌ يُفَارِقُ الْجَمَاعَةَ شِبْرًا فَيَمُوتُ إِلاَّ مَاتَ مِيتَةً جَاهِلِيَّةً ".
Narrated Ibn `Abbas:The Prophet (ﷺ) said, "If somebody sees his Muslim ruler doing something he disapproves of, he should be patient, for whoever becomes separate from the Muslim group even for a span and then dies, he will die as those who died in the Pre-Islamic period of ignorance (as rebellious sinners). (See Hadith No. 176 and)
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.
