Sahih Muslim , Book 27, Hadith 87 (In-Book) ⓘ

Jabir is reported to have said: A person amongst the Ansar who had no other property declared a slave free after his death. Allah's Messenger sold him, and Ibn al-Nahham bought him and he was a Coptic slave (who) died in the first year of the Caliphate of Ibn Zubair.

وَحَدَّثَنَاهُ أَبُو بَكْرِ بْنُ أَبِي شَيْبَةَ، وَإِسْحَاقُ بْنُ إِبْرَاهِيمَ، عَنِ ابْنِ عُيَيْنَةَ، قَالَ أَبُو بَكْرٍ حَدَّثَنَا سُفْيَانُ بْنُ عُيَيْنَةَ، قَالَ سَمِعَ عَمْرٌو، جَابِرًا يَقُولُ دَبَّرَ رَجُلٌ مِنَ الأَنْصَارِ غُلاَمًا لَهُ لَمْ يَكُنْ لَهُ مَالٌ غَيْرُهُ فَبَاعَهُ رَسُولُ اللَّهِ صلى الله عليه وسلم ‏.‏ قَالَ جَابِرٌ فَاشْتَرَاهُ ابْنُ النَّحَّامِ عَبْدًا قِبْطِيًّا مَاتَ عَامَ أَوَّلَ فِي إِمَارَةِ ابْنِ الزُّبَيْرِ ‏.‏
