The Prophet ﷺ said, "Whoever notices something which he dislikes done by his ruler, then he should be patient, for whoever becomes separate from the company of the Muslims even for a span and then dies, he will die as those who died in the Pre-lslamic period of Ignorance (as rebellious sinners). (Fath-ul-Bari page 112, Vol. 16)
عَنِ النَّبِيِّ ﷺ قَالَ مَنْ رَأَى مِنْ أَمِيرِهِ شَيْئًا يَكْرَهُهُ فَلْيَصْبِرْ عَلَيْهِ فَإِنَّهُ مَنْ فَارَقَ الْجَمَاعَةَ شِبْرًا فَمَاتَ إِلاَّ مَاتَ مِيتَةً جَاهِلِيَّةً
