"I saw the Prophet [SAW] on the Minbar addressing the people. He said: 'After me there will be many calamities and much evil behavior. Whoever you see splitting away from the Jama'ah or trying to create division among the Ummah of Muhammad [SAW], then kill him, for the Hand of Allah is with the Jama'ah, and the Shaitan is with the one who splits away from the Ummah, running with him.'" (Using translation from Nasāʾī 4020)
رَأَيْتُ النَّبِيَّ ﷺ وَهُوَ عَلَى الْمِنْبَرِ يَخْطُبُ النَّاسَ فَقَالَ «إِنَّهُ سَيَكُونُ بَعْدِي هَنَاتٌ وَهَنَاتٌ فَمَنْ رَأَيْتُمُوهُ فَارَقَ الْجَمَاعَةَ أَوْ يُرِيدُ أَنْ يُفَرِّقُ أَمْرَ أُمَّةِ مُحَمَّدٍ ﷺ كَائِنًا مَنْ كَانَ فَاقْتُلُوهُ فَإِنَّ يَدَ اللهِ عَلَى الْجَمَاعَةِ وَإِنَّ الشَّيْطَانَ مَعَ مَنْ فَارَقَ الْجَمَاعَةَ يَرْكُضُ»
