"Zakāt" () is the Islamic equivalent of a luxury tax. It was taken from the Muslims in the amount of 2.5% of their dormant wealth ("viz.", that over a certain amount unused for a year) to give to the poor. All and only those persons whose annual wealth exceeded a minimum level (nisab) were collected from. The "nisab" did not include one's primary residence, primary transportation, a moderate amount of woven jewelry, etc. "Zakāt" is one of the Five Pillars of Islam.
