Treasures buried in the earth, particularly those treasures which have been buried at some remote period.
In the Hidayah, the word rikaz includes kanz “treasure,” or other property buried in the earth, and ma’din “mines.” Such treasures are subject to a zakat of a fifth. (Hamilton’s Hidayah, vol. i. p. 39.)
