حَدَّثَنَا مُحَمَّدُ بْنُ صَبَّاحٍ، حَدَّثَنَا إِسْمَاعِيلُ بْنُ زَكَرِيَّاءَ، حَدَّثَنَا بُرَيْدُ بْنُ عَبْدِ اللَّهِ، عَنْ أَبِي بُرْدَةَ، عَنْ أَبِي مُوسَى ـ رضى الله عنه ـ قَالَ سَمِعَ النَّبِيُّ صلى الله عليه وسلم رَجُلاً يُثْنِي عَلَى رَجُلٍ، وَيُطْرِيهِ فِي مَدْحِهِ فَقَالَ " أَهْلَكْتُمْ ـ أَوْ قَطَعْتُمْ ـ ظَهْرَ الرَّجُلِ ".
