To be eligible to receive Zakat , the recipient must be poor and/or needy. A poor person is someone whose property, in excess of his basic requirements, does not reach the nisab threshold.
The recipient must not belong to your immediate family; your spouse, children, parents and grandparents cannot receive your Zakat. Other relatives, however, can receive your zakat.
Above all, it is essential to determine who is eligible to receive Zakat. This forms part of the validity of your Zakat donation. Zakat is not a form of Sadaqah (voluntary charity).
Zakat is an obligatory form of charity. Every Muslim who meets the eligibility criterion must pay Zakat. The donations are then re-distributed to the Muslim community on an annual basis.
