Zakat (Arabic: زكاة) is one of the five most important aspects of Islam. Zakat means giving charity to the poor. Generally, a Muslim is expected to give zakat as long as they are able. It is considered to be a personal responsibility for Muslims to help those in need and eliminate inequality. It is often 1/40th of what the Muslim has.
