A person amongst the Ansar who had no other property declared a slave free after his death. Messenger of Allah ﷺ 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.  

سَمِعَ عَمْرٌو جَابِرًا يَقُولُ دَبَّرَ رَجُلٌ مِنَ الأَنْصَارِ غُلاَمًا لَهُ لَمْ يَكُنْ لَهُ مَالٌ غَيْرُهُ فَبَاعَهُ رَسُولُ اللَّهِ ﷺ قَالَ جَابِرٌ فَاشْتَرَاهُ ابْنُ النَّحَّامِ عَبْدًا قِبْطِيًّا مَاتَ عَامَ أَوَّلَ فِي إِمَارَةِ ابْنِ الزُّبَيْرِ  

“A man among us promised freedom to a slave after his death, and he did not have any property other than him (this slave). So the Prophet ﷺ sold him, and Ibn (Nahham), a man from Banu 'Adi, bought him.”  

دَبَّرَ رَجُلٌ مِنَّا غُلاَمًا وَلَمْ يَكُنْ لَهُ مَالٌ غَيْرُهُ فَبَاعَهُ النَّبِيُّ ﷺ فَاشْتَرَاهُ ابْنُ النَّحَّامِ رَجُلٌ مِنْ بَنِي عَدِيٍّ  

" دَبَّرَ رَجُلٌ مِنَ الأنْصَارِ غُلاَمًا لَهُ لَمْ يَكُنْ لَهُ مَالٌ غَيْرُهُ، فَقالَ النَّبِىُّ ﷺ : مَنْ يَبْتَاعُهُ مِنِّى؟ فَاشْتَرَاهُ رَجُلٌ مِنْ بَنِى عَدِىٍّ ".
