Zakat is one of the pillars of Islam, and it is
obligatory to pay it according to the requirements.
The Promised Messiah (as) says:
"O ye people who consider themselves among my
Jama‘at, heaven will only count you in my Jama‘at
when you truly strive in the path of Taqwa. So observe
your five daily prayers with such fear and concentration
as if you actually see Allah. Complete your fasts only
for the sake of Allah with sincerity. Whoever of you is
capable to pay Zakat should do so. And whoever can
perform the Hajj, and there is no obstacle in his way, he
should perform it."
