In the Name of Allah, The Most Gracious, Ever Merciful.
Love for All, Hatred for None.
The capital levy prescribed in the Holy Quran denotes its purpose by its very name, Zakat. The word means that which purifies and fosters. By subtracting the share of the community from all wealth, the rest is purified by those entitled to make use of it; and by the application of the proceeds to the service of the community, the welfare of the community is fostered. Zakat is the third pillar of Islam and it thus reflects the importance in Islam of one's fellow beings.
And observe Prayer and pay the Zakat, and bow down will those who bow. (2:44)
So give the kinsman his due, and to the needy, and to the wayfarer. That is best for those who seek the favor of Allah, and it is they who will prosper. (30:39)
And in their wealth was a share for one who asked for help and for one would could not. (51:20)
