What is the ruling on zakat for money that a father divided and designated for his children but did not hand over to them? Instead, he kept it and managed it, earning interest on it, and then began to hand it over to his children in installments. Is it obligatory for the children to pay zakat for past periods? What is the ruling on paying zakat for future periods when the money is received? And is hoarded gold to be included with the money for zakat calculation?

The father must be advised to abandon usury and get rid of its interest. The money that has not yet been received is not subject to zakat for the son; rather, it remains the father's property. If the money is received, the son pays zakat on it after a full lunar year has passed from the time it reaches the nisab. Scholars have differed on the estimation of the nisab, whether it is the nisab of gold or silver. The cautious approach is to use the nisab of silver, as it is more beneficial for the poor and clears one's conscience more effectively. If the money is converted into gold, then what was gold is subject to zakat based on the nisab of gold.
