(49) باب فِي الرَّجُلِ يُفَضِّلُ بَعْضَ وَلَدِهِ فِي النُّحْلِ
Narrated Al-Nu'man b. Bashir:
That his father had given him a slave. The Messenger of Allah (ﷺ) said: What is this slave ? He replied: This is my slave which my father has given me. He asked: Has he given all your brothers the same as he has given you? He replied: No. He then said: Return it, then.
