In society you can find 10% to 20% people saying prayers regularly and about 80% not very regular but 99% people don’t pay Zakat. We really need to spread awareness about it. Allah says in Holy Quran
By time, indeed, mankind is in loss, except for those who have believed and done righteous deeds and advised each other to truth and advised each other to patience.
(103 : 1-3)
And when it comes advising each other, the advising starts from home and there is no restriction of age, It is our duty that we make sure that our parents pay their zakat.
