Narrated Ibn `Abbas:
حَدَّثَنَا 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 " .
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-lslamic period of ignorance (as rebellious sinners). (See Hadith No. 176 and 177)
