We were with the Prophet ﷺ. He mentioned civil strife (fitnah) and expressed its gravity. We or the people said: Messenger of Allah, if this happens to us it will destroy us. The Messenger of Allah ﷺ said; No. It is enough for you that you would be killed. Sa'id said: I saw that my brethren were killed.  

كُنَّا عِنْدَ النَّبِيِّ ﷺ فَذَكَرَ فِتْنَةً فَعَظَّمَ أَمْرَهَا فَقُلْنَا أَوْ قَالُوا يَا رَسُولَ اللَّهِ لَئِنْ أَدْرَكَتْنَا هَذِهِ لَتُهْلِكَنَّا فَقَالَ رَسُولُ اللَّهِ ﷺ كَلاَّ إِنَّ بِحَسْبِكُمُ الْقَتْلُ قَالَ سَعِيدٌ فَرَأَيْتُ إِخْوَانِي قُتِلُوا  

The Prophet ﷺ said: This people of mine is one to which mercy is shown. It will have no punishment in the next world, but its punishment in this world will be trials, earthquakes and being killed.  

قَالَ رَسُولُ اللَّهِ ﷺ أُمَّتِي هَذِهِ أُمَّةٌ مَرْحُومَةٌ لَيْسَ عَلَيْهَا عَذَابٌ فِي الآخِرَةِ عَذَابُهَا فِي الدُّنْيَا الْفِتَنُ وَالزَّلاَزِلُ وَالْقَتْلُ
