Zakah on money a woman deposited with her father for several years

The questioner:
May Allah reward you. A woman gave her father a sum of money to keep for her. She says, “If he gives me the money, I will take it; if he does not give it to me, I will leave it with him.” After several years, the father gave his daughter the money. Is she required to pay zakah for the past years?

The Shaykh:
We repeat the question.

The questioner:
A woman gave her father a sum of money and said, “If my father returns it to me, I will take it; if he does not return it to me, I will not ask him for it.” After several years, the father returned the money to his daughter. Is she required to pay zakah on it for the past years?

The Shaykh:
No, it is not obligatory for her because she does not know whether it will be returned or not. She pays zakah on it for the year in which he gave it to her. As for the past years, she owes nothing because she does not know whether it will be returned or not. Yes.
