The rate due on them is one quarter of one tenth (2.5%) once the nisab has been reached. The nisab for gold, measured in mithqals, is twenty mithqals; expressed in dinars it is twenty-five and one-seventh, plus nine-tenths, of a dinar. The nisab for silver is two hundred dirhams.

Gold and silver may be combined to complete the nisab, and the owner may discharge the zakah from whichever of the two he prefers.
