Warnings for those who don’t give Zakaat
The importance of Zakaat can also be understood with the fact that very stern warnings and chastisements have been given to those who don’t give Zakaat. They have been frightened with humiliating and painful punishment so that they refrain from their error and give the poor and the needy the rights due to them. Allah Most High says:
And those who are niggardly in giving away (from the wealth) which Allah has bestowed upon them out of His bounty must never consider this miserliness of any benefit for themselves; it is rather injurious to them. Soon on the Day of Resurrection this wealth, which they are niggardly about, will be put around (their necks) like a neck-fetter. To Allah belongs the heritage of the heavens and the earth (i.e. He will remain the Owner of the universe after your death in the same way as He owns it today). And Allah is Well Aware of all your deeds. Surah Al Imran (3:180)
