الطبراني:١٧٧٢١ – حَدَّثَنَا مُحَمَّدُ بْنُ أَحْمَدَ بْنِ أَبِي خَيْثَمَةَ ثنا أَبُو هَمَّامٍ الْوَلِيدُ بْنُ شُجَاعٍ ثنا سَعِيدُ بْنُ الْفَضْلِ الْقُرَشِيُّ ثنا سَعِيدُ بْنُ إِيَاسٍ الْجُرَيْرِيُّ عَنْ أَبِي عَبْدِ اللهِ الْعَنَزِيِّ عَنْ مَعْقِلِ بْنِ يَسَارٍ قَالَ

قَالَ رَسُولُ اللهِ ﷺ «مَنِ اشْتَرَى رَقَبَةً لِيُعْتِقَهَا فَلَا يَشْتَرِطْ لِأَهْلِهَا الْعِتْقَ فَإِنَّهُ عَقْدُهُ مِنَ الرِّقِّ»
