Don't worry, zakat is another Islamic concept the clergy (I think that's the right English word) abuse and twist to line their pockets. Zakat and khons are both about donating to the needy, but both ideas have been twisted so many times. Khons details are different but the word is related to the number 5. The first version I remember being told is that you pay one fifth of your yearly earnings' leftovers.
