Zakat (Wealth Tax)
It is incumbent upon everyone to pay wealth-tax on gold, silver, cattle and agricultural produce, when all conditions are fulfilled. This contribution is termed Zakat and should be paid to the poor having a right to it.
The Quran has commanded the payment of "Zakat"; almost as vigorously as the saying of prayers so much so that almost every verse which speaks of saying of prayers speaks of payment of zakat,
For example:
“And offer prayers and pay zakat and bow down with those who bow down (in worship)”. (2:43)
