Sunan an-Nasai
أَخْبَرَنَا أَحْمَدُ بْنُ عَمْرِو بْنِ السَّرْحِ، قَالَ أَنْبَأَنَا ابْنُ وَهْبٍ، قَالَ أَخْبَرَنِي مَالِكٌ، وَعَبْدُ اللَّهِ بْنُ عُمَرَ، وَأُسَامَةُ بْنُ زَيْدٍ، وَيُونُسُ بْنُ يَزِيدَ، أَنَّ نَافِعًا، أَخْبَرَهُمْ عَنْ عَبْدِ اللَّهِ بْنِ عُمَرَ، أَنَّ النَّبِيَّ صلى الله عليه وسلم قَالَ " مَنْ حَمَلَ عَلَيْنَا السِّلاَحَ فَلَيْسَ مِنَّا " .
It was narrated from 'Abdullah bin 'Umar that : The Prophet [SAW] said: "Whoever bears weapons against us, he is not one of us."
