أَخْبَرَنَا مُحَمَّدُ بْنُ الْمُثَنَّى، عَنْ عَبْدِ الرَّحْمَنِ بْنِ مَهْدِيٍّ، قَالَ حَدَّثَنَا حَرْبُ بْنُ شَدَّادٍ، عَنْ يَحْيَى، عَنْ أَبِي سَلَمَةَ بْنِ عَبْدِ الرَّحْمَنِ، عَنْ بُسْرِ بْنِ سَعِيدٍ، عَنْ زَيْدِ بْنِ خَالِدٍ الْجُهَنِيِّ، قَالَ قَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم " مَنْ جَهَّزَ غَازِيًا فَقَدْ غَزَا وَمَنْ خَلَفَ غَازِيًا فِي أَهْلِهِ بِخَيْرٍ فَقَدْ غَزَا " .
