Nu'man b. Bashir reported that his father brought him to Messenger of Allah ﷺ and said: I have donated this slave of mine to my son. Messenger of Allah ﷺ said: Have you donated to every one of your sons (a slave) like this? He said: No. Thereupon Allah's Messenger (may peace he upon him) said: Then take him back.

حَدَّثَنَا يَحْيَى بْنُ يَحْيَى، قَالَ قَرَأْتُ عَلَى مَالِكٍ عَنِ ابْنِ شِهَابٍ، عَنْ حُمَيْدِ بْنِ عَبْدِ، الرَّحْمَنِ وَعَنْ مُحَمَّدِ بْنِ النُّعْمَانِ بْنِ بَشِيرٍ، يُحَدِّثَانِهِ عَنِ النُّعْمَانِ بْنِ بَشِيرٍ، أَنَّهُ قَالَ إِنَّ أَبَاهُ أَتَى بِهِ رَسُولَ اللَّهِ ﷺ فَقَالَ إِنِّي نَحَلْتُ ابْنِي هَذَا غُلاَمًا كَانَ لِي . فَقَالَ رَسُولُ اللَّهِ ﷺ " أَكُلَّ وَلَدِكَ نَحَلْتَهُ مِثْلَ هَذَا " . فَقَالَ لاَ . فَقَالَ رَسُولُ اللَّهِ ﷺ " فَارْجِعْهُ " .
