Nisab

In Sharia (Islamic Law) niṣāb (نِصاب) is the minimum amount that a Muslim must have before being obliged to give zakat. Zakat is determined based on the amount of wealth acquired; the greater one's assets, the greater the zakat value. Unlike income tax in secular states niṣāb is not subject to special exemptions.

Each category of zakatable valuables has its own niṣāb. The niṣāb of gold is 20 dinārs and the nisab of silver is 200 dirhams for silver[1] based on the original 1 to 10 exchange rate. The niṣāb of crops is five wasaq, and the nisab of livestock varies depending on the type of animal.[2]
