Zakah is one of the five pillars of Islam and is a duty performed on a regular basis. Zakah is not an option it is a compulsory act for all Muslims. It is a contribution paid once a year on savings of two and a half percent. This giving is to cleanse ? your money and possessions from excessive desire for them or greed. The idea is, that by giving this money you learn not to place too much importance on material wealth (cash and possessions).
