حَدَّثَنَا أَبُو بَكْرِ بْنُ أَبِي شَيْبَةَ، وَعَبْدُ اللَّهِ بْنُ بَرَّادٍ الأَشْعَرِيُّ، وَأَبُو كُرَيْبٍ قَالُوا حَدَّثَنَا أَبُو أُسَامَةَ، عَنْ بُرَيْدٍ، عَنْ أَبِي بُرْدَةَ، عَنْ أَبِي مُوسَى، عَنِ النَّبِيِّ صلى الله عليه وسلم قَالَ " مَنْ حَمَلَ عَلَيْنَا السِّلاَحَ فَلَيْسَ مِنَّا " .
It is narrated on the authority of Abu Musa Ash'ari: He who took up arms against us is not of us.
