nasai-kubra:8505Muḥammad b. ʿAbd al-Aʿlá > al-Muʿtamir from my father > Abū Naḍrah > Abū Saʿīd > Nabī Allāh ﷺ

[Machine] He mentioned to his nation a group of people who will emerge among the people, their characteristic being that they have shaved heads. They will abandon religion as an arrow passes swiftly through its target. They are the worst of creation or the worst amongst creation. You will kill them, O people of Iraq.  

الكبرى للنسائي:٨٥٠٥أَخْبَرَنَا مُحَمَّدُ بْنُ عَبْدِ الْأَعْلَى قَالَ حَدَّثَنَا الْمُعْتَمِرُ قَالَ سَمِعْتُ أَبِي قَالَ حَدَّثَنَا أَبُو نَضْرَةَ عَنْ أَبِي سَعِيدٍ عَنْ نَبِيِّ اللهِ ﷺ

أَنَّهُ ذَكَرَ نَاسًا فِي أُمَّتِهِ يَخْرُجُونَ فِي فِرْقَةٍ مِنَ النَّاسِ سِيمَاهُمُ التَّحْلِيقُ يَمْرُقُونَ مِنَ الدِّينِ كَمَا يَمْرُقُ السَّهْمُ مِنَ الرَّمِيَّةِ هُمْ مِنْ شَرِّ الْخَلْقِ أَوْ هُمْ شَرُّ الْخَلْقِ تَقْتُلُهُمْ أَدْنَى الطَّائِفَتَيْنِ إِلَى الْحَقِّ قَالَ وَقَالَ كَلِمَةً أُخْرَى قُلْتُ بَيْنِي وَبَيْنَهُ مَا هِيَ؟ قَالَ «وَأَنْتُمْ قَتَلْتُمُوهُمْ يَا أَهْلَ الْعِرَاقِ»
