Designating a specific day of the year for paying zakah

Question:
The questioner asks: Is the method of designating a specific day of the year for paying zakah valid or not?

Answer:
No, it is not valid. Zakah is contingent upon the completion of the lunar year. When the lunar year is completed and he possesses the minimum threshold, the year has been completed for him, and it becomes obligatory to pay the zakah immediately, meaning at that very moment, and he must not delay it until another time. This is because, first, of the need of the poor, and because Allah said, “And give the zakah,” and the command implies immediacy. Second, the need of the poor is present, so how can you withhold the zakah from them until Ramadan comes? Pay the zakah when it becomes obligatory. And Allah the Exalted said regarding crops: on the day of its harvest, meaning at the time of obtaining it. Yes.
