باب الأَمْرِ بِلُزُومِ الْجَمَاعَةِ عِنْدَ ظُهُورِ الْفِتَنِ وَتَحْذِيرِ الدُّعَاةِ إِلَى الْكُفْرِ ‏‏
Sahih Muslim 1851 a

It has been reported on the authority of Nafi, that 'Abdullah b. Umar paid a visit to Abdullah b. Muti' in the days (when atrocities were perpetrated on the People Of Medina) at Harra in the time of Yazid b. Mu'awiya. Ibn Muti' said:

Place a pillow for Abu 'Abd al-Rahman (family name of 'Abdullah b. 'Umar). But the latter said: I have not come to sit with you. I have come to you to tell you a tradition I heard from the Messenger of Allah (ﷺ). I heard him say: One who withdraws his band from obedience (to the Amir) will find no argument (in his defence) when he stands before Allah on the Day of Judgment, and one who dies without having bound himself by an oath of allegiance (to an Amir) will die the death of one belonging to the days of Jahillyya.
حَدَّثَنَا عُبَيْدُ اللَّهِ بْنُ مُعَاذٍ الْعَنْبَرِيُّ، حَدَّثَنَا أَبِي، حَدَّثَنَا عَاصِمٌ، - وَهُوَ ابْنُ مُحَمَّدِ بْنِ زَيْدٍ - عَنْ زَيْدِ بْنِ مُحَمَّدٍ، عَنْ نَافِعٍ، قَالَ جَاءَ عَبْدُ اللَّهِ بْنُ عُمَرَ إِلَى عَبْدِ اللَّهِ بْنِ مُطِيعٍ حِينَ كَانَ مِنْ أَمْرِ الْحَرَّةِ مَا كَانَ زَمَنَ يَزِيدَ بْنِ مُعَاوِيَةَ فَقَالَ اطْرَحُوا لأَبِي عَبْدِ الرَّحْمَنِ وِسَادَةً فَقَالَ إِنِّي لَمْ آتِكَ لأَجْلِسَ أَتَيْتُكَ لأُحَدِّثَكَ حَدِيثًا سَمِعْتُ رَسُولَ اللَّهِ صلى الله عليه وسلم يَقُولُهُ سَمِعْتُ رَسُولَ اللَّهِ صلى الله عليه وسلم يَقُولُ ‏ "‏ مَنْ خَلَعَ يَدًا مِنْ طَاعَةٍ لَقِيَ اللَّهَ يَوْمَ الْقِيَامَةِ لاَ حُجَّةَ لَهُ وَمَنْ مَاتَ وَلَيْسَ فِي عُنُقِهِ بَيْعَةٌ مَاتَ مِيتَةً جَاهِلِيَّةً ‏"‏ ‏.‏
