Also called Zakat-ul-Fitr is the charity that Muslims must pay in at the end Ramadan before Eid prayer. This payment is intended to give those in poverty the opportunity to participate in Eid-ul-Fitr.
In Islam there are two kinds of charity, Zakat (compulsory) and Sadqah (optional). Both types of charities have benefits and are encouraged not just to support the poor and needy but to purify your money, alleviate trial and tribulations, and increase your piety.
