[Machine] I heard the Messenger of Allah ﷺ saying near the chamber of Aisha, "On the Day of Judgment, a banner will be raised for every betrayer, and there is no betrayal greater than the betrayal of a general leader."  

أحمد:٥٣٧٨حَدَّثَنَا حَسَنُ بْنُ مُوسَى حَدَّثَنَا حَمَّادُ بْنُ زَيْدٍ عَنْ بِشْرِ بْنِ حَرْبٍ سَمِعْتُ ابْنَ عُمَرَ يَقُولُ

سَمِعْتُ رَسُولَ اللهِ ﷺ عِنْدَ حُجْرَةِ عَائِشَةَ يَقُولُ يُنْصَبُ لِكُلِّ غَادِرٍ لِوَاءٌ يَوْمَ الْقِيَامَةِ وَلَا غَدْرَةَ أَعْظَمُ مِنْ غَدْرَةِ إِمَامِ عَامَّةٍ
