Zakah is the third pillar of Islam that refers to the obligatory charity tax paid annually by Muslims. There are two main types of zakah: zakat al-fitr paid during Ramadan to the poor; and zakat al-mal which is 2.5% of excess wealth paid to the poor and needy. Zakah aims to purify wealth and eliminate poverty by distributing wealth from the rich to eight categories of recipients, including the poor, debtors, and those working to collect zakah. Payment of zakah is an important religious obligation in Islam.
