" Kill all of them." I heard the Messenger of Allah ﷺ say: When you are holding to one single man as your leader, you should kill who seeks to undermine your solidarity or disrupt your unity.
سَمِعْتُ رَسُولَ اللَّهِ ﷺ يَقُولُ مَنْ أَتَاكُمْ وَأَمْرُكُمْ جَمِيعٌ عَلَى رَجُلٍ وَاحِدٍ يُرِيدُ أَنْ يَشُقَّ عَصَاكُمْ أَوْ يُفَرِّقَ جَمَاعَتَكُمْ فَاقْتُلُوهُ
