باب عِتْقِ الْمُدَبَّرِ وَأُمِّ الْوَلَدِ وَالْمُكَاتَبِ فِي الْكَفَّارَةِ، وَعِتْقِ وَلَدِ الزِّنَا
Sahih al-Bukhari 6716

Narrated `Amr:

Jabir said: An Ansari man made his slave a Mudabbar and he had no other property than him. When the Prophet (ﷺ) heard of that, he said (to his companions), "Who wants to buy him (i.e., the slave) for me?" Nu'aim bin An-Nahham bought him for eight hundred Dirhams. I heard Jabir saying, "That was a coptic slave who died in the same year."

حَدَّثَنَا أَبُو النُّعْمَانِ، أَخْبَرَنَا حَمَّادُ بْنُ زَيْدٍ، عَنْ عَمْرٍو، عَنْ جَابِرٍ، أَنَّ رَجُلاً، مِنَ الأَنْصَارِ دَبَّرَ مَمْلُوكًا لَهُ، وَلَمْ يَكُنْ لَهُ مَالٌ غَيْرُهُ فَبَلَغَ النَّبِيَّ صلى الله عليه وسلم فَقَالَ ‏ "‏ مَنْ يَشْتَرِيهِ مِنِّي ‏"‏‏.‏ فَاشْتَرَاهُ نُعَيْمُ بْنُ النَّحَّامِ بِثَمَانِمِائَةِ دِرْهَمٍ، فَسَمِعْتُ جَابِرَ بْنَ عَبْدِ اللَّهِ يَقُولُ عَبْدًا قِبْطِيًّا مَاتَ عَامَ أَوَّلَ‏.‏
