A son borrowed from his father. When the time for zakah arrives, does he pay zakah on his money and this borrowed amount?

Question:
May Allah reward you, Honorable Shaykh. This questioner says: A son borrowed a sum of money from his father. When the time for zakah arrives, does he pay zakah on his money and this borrowed amount? And does his father also have to pay zakah on the amount he lent to his son?

Answer:
Zakah becomes obligatory on the owner of the wealth when the lunar year has passed. Zakah is obligatory on the one who owns the wealth, whether the wealth is in his hand or it is a debt in the hands of people, because it is his property that he pays zakah on. The debtor pays zakah on what he owns. Everyone pays zakah on what is in his hand. The debtor pays zakah on what is in his hand and what he owns, and the creditor pays zakah on what is in his hand and what he owns. Yes.
