Sahih Muslim , Hadith 1065

Abu Sa'id al-Khudri said that the Messenger of Allah made a mention of a sect that would be among his Ummah which would emerge out of the dissension of the people. Their distinctive mark would be shaven heads. They would be the worst creatures or the worst of the creatures. The group who would be nearer to the truth out of the two would kill them. The Apostle of Allah gave an example (to give their description) or he said: A man throws an arrow at the prey (or he said at the target), and sees at its iron head, but finds no sign (of blood there), or he sees at the lowest end, but would not see or find any sign (of blood there). He would then see into the grip but would not find (anything) sticking to it. Abu Sai'd then said: People of Iraq. it is you who have killed them.

وَحَدَّثَنِي مُحَمَّدُ بْنُ الْمُثَنَّى، حَدَّثَنَا ابْنُ أَبِي عَدِيٍّ، عَنْ سُلَيْمَانَ، عَنْ أَبِي نَضْرَةَ، عَنْ أَبِي سَعِيدٍ، أَنَّ النَّبِيَّ صلى الله عليه وسلم ذَكَرَ قَوْمًا يَكُونُونَ فِي أُمَّتِهِ يَخْرُجُونَ فِي فُرْقَةٍ مِنَ النَّاسِ سِيمَاهُمُ التَّحَالُقُ قَالَ ‏"‏ هُمْ شَرُّ الْخَلْقِ - أَوْ مِنْ أَشَرِّ الْخَلْقِ - يَقْتُلُهُمْ أَدْنَى الطَّائِفَتَيْنِ إِلَى الْحَقِّ ‏"‏ ‏.‏ قَالَ فَضَرَبَ النَّبِيُّ صلى الله عليه وسلم لَهُمْ مَثَلاً أَوْ قَالَ قَوْلاً ‏"‏ الرَّجُلُ يَرْمِي الرَّمِيَّةَ - أَوْ قَالَ الْغَرَضَ - فَيَنْظُرُ فِي النَّصْلِ فَلاَ يَرَى بَصِيرَةً وَيَنْظُرُ فِي النَّضِيِّ فَلاَ يَرَى بَصِيرَةً وَيَنْظُرُ فِي الْفُوقِ فَلاَ يَرَى بَصِيرَةً ‏"‏ ‏.‏ قَالَ قَالَ أَبُو سَعِيدٍ وَأَنْتُمْ قَتَلْتُمُوهُمْ يَا أَهْلَ الْعِرَاقِ ‏.‏

Abu Sa'id al-Khudri reported that the Messenger of Allah said: A group would secede itself (from the Ummah) when there would be dissension among the Muslims. Out of the two groups who would be nearer the truth would kill them.

حَدَّثَنَا شَيْبَانُ بْنُ فَرُّوخَ، حَدَّثَنَا الْقَاسِمُ، - وَهُوَ ابْنُ الْفَضْلِ الْحُدَّانِيُّ - حَدَّثَنَا أَبُو نَضْرَةَ، عَنْ أَبِي سَعِيدٍ الْخُدْرِيِّ، قَالَ قَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم ‏ "‏ تَمْرُقُ مَارِقَةٌ عِنْدَ فُرْقَةٍ مِنَ الْمُسْلِمِينَ يَقْتُلُهَا أَوْلَى الطَّائِفَتَيْنِ بِالْحَقِّ ‏" ‏ ‏.‏

حَدَّثَنَا أَبُو الرَّبِيعِ الزَّهْرَانِيُّ، وَقُتَيْبَةُ بْنُ سَعِيدٍ، قَالَ قُتَيْبَةُ حَدَّثَنَا أَبُو عَوَانَةَ، عَنْ قَتَادَةَ، عَنْ أَبِي نَضْرَةَ، عَنْ أَبِي سَعِيدٍ الْخُدْرِيِّ، قَالَ قَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم ‏ "‏ تَكُونُ فِي أُمَّتِي فِرْقَتَانِ فَتَخْرُجُ مِنْ بَيْنِهِمَا مَارِقَةٌ يَلِي قَتْلَهُمْ أَوْلاَهُمْ بِالْحَقِّ ‏" ‏ ‏.‏

حَدَّثَنِي عُبَيْدُ اللَّهِ الْقَوَارِيرِيُّ، حَدَّثَنَا مُحَمَّدُ بْنُ عَبْدِ اللَّهِ بْنِ الزُّبَيْرِ، حَدَّثَنَا سُفْيَانُ، عَنْ حَبِيبِ بْنِ أَبِي ثَابِتٍ، عَنِ الضَّحَّاكِ الْمِشْرَقِيِّ، عَنْ أَبِي سَعِيدٍ الْخُدْرِيِّ، عَنِ النَّبِيِّ صلى الله عليه وسلم فِي حَدِيثٍ ذَكَرَ فِيهِ قَوْمًا يَخْرُجُونَ عَلَى فُرْقَةٍ مُخْتَلِفَةٍ يَقْتُلُهُمْ أَقْرَبُ الطَّائِفَتَيْنِ مِنَ الْحَقِّ ‏.‏
