Queastion and Answers:-, Is it permissible to discharge one’s Zakaat before the expiry of one complete lunar year?

Q: Is it permissible to discharge Zakaat on one's Zakaatable wealth
before the expiry of one completelunar year?
A: In principle, Zakaat is obligatory upon the expiry of one
completelunar year if a person is sane, mature and owns the Nisaab
amount.
However, it is permissible to discharge the Zakaat before the expiry
of one lunar year subject to the following conditions:
1) One has the intention of discharging Zakaat at the time of
giving it to the poor person,
2) One still owns the Nisaab at the end of the lunar year
3) One must at least have some wealth in his net-possession during
the entire year
(Al Fatawaa Al Hindiyyah 1/176)
One should also note down the amount discharged in advance and compare
this with the amount that is due at the end of the year. If the amount
he has paid in Zakaat is less than the amount due, then one should pay
out the difference.

And Allah Ta'ala Knows Best
