If by means of underwater diving a person acquires pearls, corals, or other gems, whether they be growing things or minerals, in the event that their value reaches eighteen nukhuds[1] of gold, he must pay khums on them – irrespective of whether they were brought up in a single dive or multiple dives – provided there is not a long interval between them; and if there is – for example, he dives in two different seasons – then, in the event that [the gems found in] each dive do not reach the value of eighteen nukhuds of gold, it is not obligatory to pay khums on them.
Similarly, if the share of each diver taking part in the dive does not reach the value of eighteen nukhuds of gold, it is not obligatory to pay khums on it.
