In Islam, Zakat is the fourth pillar. Zakat refers to purification in general and purification of wealth in particular, therefore, those Muslims who have wealth over a certain ratio, they are liable to pay Zakat on it and give it to those who are less fortunate and don’t have sufficient means to live their life in a standard way.
Pertaining to the question of Zakat, the skeptic ones ask the question that why do they have to pay from their earned money and wealth to the others? The answer to which is as follows.
Besides the fact that Zakat is an obligation and fulfillment of it leads to a Muslim getting reward from Allah Almighty and intentional swerving from it leads to a Muslim receiving punishment from Him, there are other reasons which one can find pertaining to the importance of Zakat.
