[Machine] I saw Abu Masood when Ali was killed, so I followed him and said, "I urge you by Allah, what did you hear from the Prophet ﷺ regarding trials?" He said, "We do not hide anything from you out of fear of Allah, and we advise you to fear Allah and stick to the community. Beware of division, for it is misguidance. Indeed, Allah ﷻ would never gather the nation of Muhammad ﷺ on misguidance."  

الطبراني:١٤٧٩٤حَدَّثَنَا عَلِيُّ بْنُ عَبْدِ الْعَزِيزِ ثَنَا ابْنُ الْأَصْبَهَانِيِّ ثَنَا شَرِيكٌ عَنْ قَيْسِ بْنِ يَسِيرِ بْنِ عَمْرٍو عَنْ أَبِيهِ قَالَ

رَأَيْتُ أَبَا مَسْعُودٍ لَمَّا قُتِلَ عَلِيٌّ فَتَبِعْتُهُ فَقُلْتُ أَنْشُدُكَ اللهَ مَا سَمِعْتَ مِنَ النَّبِيِّ ﷺ فِي الْفِتَنِ؟ فَقَالَ «إِنَّا لَا نَكْتُمُ شَيْئًا عَلَيْكَ بِتَقْوَى اللهِ وَالْجَمَاعَةِ وَإِيَّاكَ وَالْفُرْقَةَ فَإِنَّهَا هِيَ الضَّلَالُ وَإنَّ اللهَ ﷻ لَمْ يَكُنْ لَيَجْمَعَ أُمَّةَ مُحَمَّدٍ ﷺ عَلَى ضَلَالَةٍ»
