All perfect praise be to Allah, The Lord of the Worlds. I testify that there is none worthy of worship except Allah, and that Muhammad is His slave and Messenger.
As for the Zakat on money, it is paid out to its beneficiaries including the poor, the needy, etc. It is not bought food or any other thing with the money of Zakat. In truth, the poor are more aware of their needs. As such, whoever wants to buy any items for the poor, he should do so with the money of the recommended charity, not the obligatory Zakat.
Allah knows the best.
