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-lslamic period of ignorance (as rebellious sinners). (See Hadith No. 176 and 177)

حَدَّثَنَا سُلَيْمَانُ بْنُ حَرْبٍ، حَدَّثَنَا حَمَّادٌ، عَنِ الْجَعْدِ، عَنْ أَبِي رَجَاءٍ، عَنِ ابْنِ عَبَّاسٍ، يَرْوِيهِ قَالَ قَالَ النَّبِيُّ ﷺ " مَنْ رَأَى مِنْ أَمِيرِهِ شَيْئًا فَكَرِهَهُ فَلْيَصْبِرْ، فَإِنَّهُ لَيْسَ أَحَدٌ يُفَارِقُ الْجَمَاعَةَ شِبْرًا فَيَمُوتُ إِلاَّ مَاتَ مِيتَةً جَاهِلِيَّةً ".
