حَدَّثَنَا أَبُو الرَّبِيعِ الزَّهْرَانِيُّ، حَدَّثَنَا يَزِيدُ، - يَعْنِي ابْنَ زُرَيْعٍ - حَدَّثَنَا حُسَيْنٌ، الْمُعَلِّمُ حَدَّثَنَا يَحْيَى بْنُ أَبِي كَثِيرٍ، عَنْ أَبِي سَلَمَةَ بْنِ عَبْدِ الرَّحْمَنِ، عَنْ بُسْرِ بْنِ سَعِيدٍ، عَنْ زَيْدِ بْنِ خَالِدٍ الْجُهَنِيِّ، قَالَ قَالَ نَبِيُّ اللَّهِ صلى الله عليه وسلم ‏
"‏ مَنَ جَهَّزَ غَازِيًا فَقَدْ غَزَا وَمَنْ خَلَفَ غَازِيًا فِي أَهْلِهِ فَقَدْ غَزَا ‏"‏ ‏.‏
