Zakat al-Fitr is a duty incumbent on every Muslim. Ibn 'Umar reports: ‘Allah’s messenger made the Zakat al-Fitr, a sa' of dates or barley, binding on every Muslim: slave or free, male or female, young or old.

Scholars agree that Zakat is due on jewelry kept as savings. But they differ in their view on jewelry kept for permissible use. As a conclusion, zakat is not due on usable jewelry if it is within reasonable limits.
The zakat payable on gold and silver is 2.5 %, which means that for 20 dinars (a dinar was the gold currency) half a dinar is payable. For any little or great amount above that the same rate of 2.5 % applies.
If the borrower is facing hardship and cannot repay the debt, the lender pays zakat for the loan once it is repaid. If it had been with the borrower for several years, the lender pays its zakat for one year only. On the other hand, if the loan is given to someone who has money and is able to repay it, its zakat is due on the lender every year, because financial instruments being with someone able to repay them is like its being with the lender.
