أحمد:٥١٤٩حَدَّثَنَا يَحْيَى بْنُ سَعِيدٍ عَنْ عُبَيْدِ اللهِ أَخْبَرَنِي نَافِعٌ عَنْ عَبْدِ اللهِ قَالَ

قَالَ رَسُولُ اللهِ ﷺ وَعَبْدُ الرَّحْمَنِ عَنْ مَالِكٍ عَنْ نَافِعٍ عَنِ ابْنِ عُمَرَ عَنِ النَّبِيِّ ﷺ قَالَ مَنْ حَمَلَ عَلَيْنَا السِّلَاحَ فَلَيْسَ مِنَّا

مسلم:٩٨حَدَّثَنِي زُهَيْرُ بْنُ حَرْبٍ وَمُحَمَّدُ بْنُ الْمُثَنَّى قَالاَ حَدَّثَنَا يَحْيَى وَهُوَ الْقَطَّانُ ح وَحَدَّثَنَا أَبُو بَكْرِ بْنُ أَبِي شَيْبَةَ حَدَّثَنَا أَبُو أُسَامَةَ وَابْنُ نُمَيْرٍ كُلُّهُمْ عَنْ عُبَيْدِ اللَّهِ عَنْ نَافِعٍ عَنِ ابْنِ عُمَرَ

عَنِ النَّبِيِّ ﷺ ح وَحَدَّثَنَا يَحْيَى بْنُ يَحْيَى وَاللَّفْظُ لَهُ قَالَ قَرَأْتُ عَلَى مَالِكٍ عَنْ نَافِعٍ عَنِ ابْنِ عُمَرَ أَنَّ النَّبِيَّ ﷺ قَالَ مَنْ حَمَلَ عَلَيْنَا السِّلاَحَ فَلَيْسَ مِنَّا
