Offering zakah is one of the main tenets of Islam.
Zakah is payable on 2.5 percent of the wealth one possesses above the nisab. Nisab, which is equal to the value of 3 ounces of gold, is the minimum amount of wealth one must have and have maintained for one lunar year before they are liable to pay zakah.
Zakah is owed on gold, silver, cash, savings, investments, rent income, business merchandise and profits, shares, securities, and bonds.
Islamic Relief collects and distributes zakah to those who are most in need, in accordance with Islamic guidelines.
