As-salaamu'alaykum,
Mu’aiqeeb related that, one day, Umar summoned for him at noon time. When Mu’aiqeeb entered upon Umar, he saw that Umar was busy demanding something from his son Aasim, Umar then stopped, turned towards Mu'aiqeeb and said to him,
"Do you know what he has done? Verily, he went to Iraq, informed the people there that he is the son of the Leader of the Believers, and asked them for spending money. They gave him dishes, gold, an adorned sword, and other items."
Aasim said,
"I did not do that; rather, all that happened was that I visited some of my people, and they then gave me (these things)."
Umar said,
"Take it, O Mu'aiqeeb, and place it in the Muslim Treasury."
(Asrul-Khilaafah ar-Raashidah, by al-Umaree, pg. 236. This narration is hasan (acceptable))
Here is an example of the person gaining wealth not through hard work, but through being one's own business card - through announcing one's title and rank, hoping that will be enough to gain some money. When Umar felt that his son received wealth because of his status, and not because he worked hard to earn it, he knew that he could not in good conscience allow his son to keep the wealth.
