Sayyiduna Ali (may Allah be pleased with him) narrates that the Messenger of Allah (peace and blessings be upon him) said: "Pay one dirham as zakat out of every forty dirhams, and there is no zakat on less than two hundred dirhams. Then, when it reaches two hundred dirhams, five dirhams are due as zakat, and whatever is more than that, zakat is obligatory on it as well at the same rate (one-fortieth part)."
