How is zakat paid on invested funds that have not yet been recovered, especially when their current value or profits are unknown? What is the ruling on zakat for capital and delayed profits? And how is zakat paid on funds used to purchase land with financial assistance from one's father that has not yet been repaid?

The rulings on Zakat can be summarized in five points:

1. Zakat on Qirad (Mudarabah) funds: If the Qirad funds are present, their owner must pay Zakat on them immediately after their calculation. However, if the funds are absent and their amount cannot be determined, the owner must wait until they can calculate them, and then pay Zakat for the past years. 2. Zakat on profits: Profits are subject to the original capital, and a new hawl (lunar year) is not awaited for them. 3. Zakat on past wealth: Zakat is obligatory for every year in which it was not paid when it became due. 4. Rectifying failure to pay Zakat on capital: It is obligatory to pay Zakat on wealth for every year in which Zakat was not paid. 5. Considering what the father paid as a debt: The father determines whether what he paid is a debt to be repaid or not. If it is a debt, it is deducted from the Zakatable wealth, provided that the son does not have non-Zakatable funds sufficient to repay the debt.
