In the event of the dissension among Muslims an emerging sect will emerge ; one of the two parties that is nearer to the truth will kill it. (Using translation from Abū Dāʾūd 4667)
أَنَّ رَسُولَ اللهِ ﷺ قَالَ «تَمْرُقُ مَارِقَةٌ عِنْدَ فِرْقَةٍ مِنَ النَّاسِ تَقْتُلُهَا أَوْلَى الطَّائِفَتَيْنِ بِالْحَقِّ»
