الطبراني:١٦٤٢٩c – حَدَّثَنَا مُحَمَّدُ بْنُ عَلِيٍّ الصَّائِغُ الْمَكِّيُّ ثنا بَكْرُ بْنُ خَلَفٍ ثنا قُدَامَةُ بْنُ مُحَمَّدٍ الْأَشْجَعِيُّ ثنا دَاوُدُ بْنُ الْمُغِيرَةِ عَنْ سَعْدِ بْنِ إِسْحَاقَ بْنِ كَعْبِ بْنِ عُجْرَةَ عَنْ أبِيهِ عَنْ جَدِّهِ

أَنَّ النَّبِيَّ ﷺ قَالَ «يَا كَعْبُ بْنَ عُجْرَةَ النَّاسُ غَادِيَانِ فَمُشْتَرٍ نَفْسَهُ فَمُعْتِقُهَا وَبَائِعٌ نَفْسَهُ فَمُهْلِكُهَا»
