Zakat is likewise due on honey, whether it is taken from one’s own property or from unclaimed land—such as mountain ridges—provided the amount collected reaches the nisab. The nisab for honey is 30 saʿs according to the Prophetic measure, and the rate due is a full tenth.

Zakat is also obligatory on mineral wealth, in view of the Divine command: “Spend of the good things you have earned and of what We bring forth for you from the earth” (Qur’an 2:267). A mine (maʿdin) is any site in which one extracts one of the earth’s precious substances; since it is something taken from the earth, zakat is required of it just as it is required of grain and fruit. If the extracted ore is gold or silver, one pays a quarter of one tenth (2.5 %) once it reaches the nisab or more. If it is something else—such as kohl (antimony), orpiment, sulfur, salt, or petroleum—then one pays a quarter of one tenth of its market value, provided that value equals or exceeds the nisab measured in gold or silver.

Zakat is likewise due on buried treasure (rikāz), meaning whatever is found interred of the wealth of pre-Islamic non-Muslims. It is called rikāz because it is hidden in the earth, as in the expression “I planted the spear.” One fifth of such treasure is payable, whether the amount be small or great, in accordance with the Prophet’s words: “On buried treasure, one fifth is due,” agreed upon. Its non-Muslim origin is recognized by the presence of their marks on all or part of it—for example, the names of their kings or the imprint of their crosses. After the fifth has been paid, the remainder belongs to the finder.
