Hadith 7:6
Narrated [Jabir bin 'Abdullah (RA)]:
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 (ﷺ) sent for him (the slave) and sold him. [Agreed upon].
وَعَنْهُ قَالَ: { أَعْتَقَ رَجُلٌ مِنَّا عَبْداً لَهُ عَنْ دُبُرٍ لَمْ يَكُنْ لَهُ مَالٌ غَيْرُهُ. فَدَعَا بِهِ اَلنَّبِيُّ - صلى الله عليه وسلم -فَبَاعَهُ } مُتَّفَقٌ عَلَيْهِ
