If a man pays his zakah before the completion of the lunar year, and then wishes to pay his zakah at the same time every year

The questioner : Shaykh, if a man pays his zakah before the completion of the lunar year, and then wishes to pay his zakah at the same time every year, is that permissible for him?

The Shaykh : It is permissible for him. Because it means he pays every year based on his year.

The questioner : Even if he thinks that if he waits until the completion of the lunar year, his wealth might increase.

The Shaykh : No, if it increases, he pays the zakah on the increase. If it increases, he pays the zakah on the increase. And if it decreases, he has chosen to be voluntary on his own and taken the zakah.
