Narrated Zaid bin Aslam:
from his father, from 'Umar, that he ('Umar) granted a stipend of three-thousand and five-hundred to Usamah bin Zaid, and he granted three-thousand to 'Abdullah bin 'Umar. So 'Abdullah bin 'Umar said to his father: "Why have you given preference to Usamah over me? For by Allah, he has not preceded me to any battle." He said: "Because Zaid used to be more beloved to the Messenger of Allah (ﷺ) than your father, and Usamah was more beloved to the Messenger of Allah (ﷺ) than you. So I gave preference to the beloved of the Messenger of Allah (ﷺ) over my beloved." (JA)
