وَعَنْ أَبِي سَعِيدٍ الْخُدْرِيِّ قَالَ: قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ: «يَكُونُ أُمَّتِي فِرْقَتَيْنِ فَيَخْرُجُ مِنْ بَيْنِهِمَا مَارِقَةٌ يَلِي قَتْلَهُمْ أولاهم بِالْحَقِّ» . رَوَاهُ مُسلم

Abu Sa'id al-Khudri reported that the Messenger of God said: ‘My community will divide into two groups, and a secessionist group will emerge from between them. The group among them that is closest to the truth will undertake killing them.’ Muslim transmitted it.
