باب الأَمْرِ بِلُزُومِ الْجَمَاعَةِ عِنْدَ ظُهُورِ الْفِتَنِ وَتَحْذِيرِ الدُّعَاةِ إِلَى الْكُفْرِ ‏‏

It has been narrated (through a different chain of transmitters) on the authority of Ibn Abbas that the Messenger of Allah (may peace be upoh him) said:

One who dislikes a thing done by his Amir should be patient over it, for anyone from the people who withdraws (his obedience) from the government, even to the extent of a handspan and died in that conditions, would die the death of one belonging to the days of jahilliyya.
وَحَدَّثَنَا شَيْبَانُ بْنُ فَرُّوخَ، حَدَّثَنَا عَبْدُ الْوَارِثِ، حَدَّثَنَا الْجَعْدُ، حَدَّثَنَا أَبُو رَجَاءٍ، الْعُطَارِدِيُّ عَنِ ابْنِ عَبَّاسٍ، عَنْ رَسُولِ اللَّهِ صلى الله عليه وسلم قَالَ ‏ "‏ مَنْ كَرِهَ مِنْ أَمِيرِهِ شَيْئًا فَلْيَصْبِرْ عَلَيْهِ فَإِنَّهُ لَيْسَ أَحَدٌ مِنَ النَّاسِ خَرَجَ مِنَ السُّلْطَانِ شِبْرًا فَمَاتَ عَلَيْهِ إِلاَّ مَاتَ مِيتَةً جَاهِلِيَّةً ‏"‏ ‏.‏
