It was narrated from Hisham bin 'Urwah, from his father, that Bashir came to the Prophet and said: "O Prophet of Allah, I have given An-Nu'man a present". He said: "Have you given something to his brothers?" He said: "No". He said: "Then take it back".
This hadith also teaches us about generosity; even though Bashir was asked to take back his gift, this does not mean that we should not give gifts at all! Rather, it means that we must be mindful of how our actions affect others around us so as not to cause any harm or hurt feelings due to unfairness or inequality.
