وَعَنْهُ قَالَ: «أَعْتَقَ رَجُلٌ مِنَّا عَبْداً لَهُ عَنْ دُبُرٍ لَمْ يَكُنْ لَهُ مَالٌ غَيْرُهُ. فَدَعَا بِهِ اَلنَّبِيُّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ فَبَاعَهُ»
A man among us declared that a slave belonging to him would be free after his death. However, he had no other property. So, the Prophet (sallallahu alayhi wa sallam) sent for him (the slave) and sold him.
