Sahih al-Bukhari, Hadith 2403 ⓘ
Narrated Jabir bin `Abdullah: A man pledged that his slave would be manumitted after his death. The Prophet asked, "Who will buy the slave from me?" Nu'aim bin `Abdullah bought the slave and the Prophet took its price and gave it to the owner.
حَدَّثَنَا مُسَدَّدٌ، حَدَّثَنَا يَزِيدُ بْنُ زُرَيْعٍ، حَدَّثَنَا حُسَيْنٌ الْمُعَلِّمُ، حَدَّثَنَا عَطَاءُ بْنُ أَبِي رَبَاحٍ، عَنْ جَابِرِ بْنِ عَبْدِ اللَّهِ ـ رضى الله عنهما ـ قَالَ أَعْتَقَ رَجُلٌ غُلاَمًا لَهُ عَنْ دُبُرٍ فَقَالَ النَّبِيُّ صلى الله عليه وسلم " مَنْ يَشْتَرِيهِ مِنِّي " . فَاشْتَرَاهُ نُعَيْمُ بْنُ عَبْدِ اللَّهِ، فَأَخَذَ ثَمَنَهُ، فَدَفَعَهُ إِلَيْهِ.
