Zakat (Poor Due, Alms)

1-The term "Zakat" originally means: growth, and purity.
2-In Islamic Law, it means paying every lunar year a certain percentage of your savings to be used in certain charitable uses defined by Al-Qur'an.
3-If you have, for that period, an amount of money equal to the value of  85 grams of pure gold (now, 1985, is about $1000) or more, you must pay 2.5%.
4-Zakat is paid for the poor and the needy Muslims, for the wayfarers, for propagating Islam or fighting for Islam, for helping new Muslims or encouraging non-Muslims to embrace Islam, for those who are burdened with debts and are unable to pay them.
5-If you have articles of trade, you calculate their Zakat in the same way.
6-You can ask some Muslim scholar or refer to any good reference book to know more about Zakat.
