A father taking from the marriage assistance that came to his son

Question:
Honorable Shaykh, he says: A man wants to get married, and he received financial assistance from his brothers, so his father took some of it to give on behalf of his young son. Is there any harm in this? And is the consent of the older son required?

Answer:
There is no harm in that. The father may take from his son’s money what does not harm him and what he does not need. If his father takes something from him, there is no harm in that, except if this harms the one who wants to get married and reduces the amount he needs. In that case, the father should not put his son in a difficult position or burden him regarding the mahr (bridal gift) he wants to use for his marriage. It is obligatory for the father to help him and to marry him off from his own funds. This is the obligation of the father.
