“O Umair, I have set you free in a good way. I heard the Messenger of Allah ﷺ say: 'Any man who frees a slave and does not say anything about his (the slave's) wealth, it belongs to him (the slave).' So tell me, how much wealth do you have?” Another chain reports a similar hadith.
لَهُ يَا عُمَيْرُ إِنِّي أُعْتِقُكَ عِتْقًا هَنِيئًا إِنِّي سَمِعْتُ رَسُولَ اللَّهِ ﷺ يَقُولُ أَيُّمَا رَجُلٍ أَعْتَقَ غُلاَمًا وَلَمْ يُسَمِّ مَالَهُ فَالْمَالُ لَهُ فَأَخْبِرْنِي مَا مَالُكَ حَدَّثَنَا مُحَمَّدُ بْنُ عَبْدِ اللَّهِ بْنِ نُمَيْرٍ حَدَّثَنَا الْمُطَّلِبُ بْنُ زِيَادٍ عَنْ إِسْحَاقَ بْنِ إِبْرَاهِيمَ قَالَ قَالَ عَبْدُ اللَّهِ بْنُ مَسْعُودٍ لِجَدِّي فَذَكَرَ نَحْوَهُ
