Explanation & Benefits
Shaykh Umar Farooq Saeedi
Benefits and Issues: Wealth buried by someone in a deserted land or in an ancient, old settlement, whose owner is unknown, is called rikaz. Whoever finds such wealth becomes its owner after paying the khums (one-fifth portion).

Sayyiduna Abu Hurairah (may Allah be pleased with him) narrates this statement of the Noble Prophet (peace and blessings be upon him): "There will be no compensation for injury caused by an animal. There will be no compensation for death by falling into a mine. There will be no compensation for death by falling into a well, and payment of one-fifth is obligatory on treasure."
Shaykh Muhammad Ibrahim bin Basheer
Benefit: In this hadith, it is stated that any harm caused by an animal's attack, or by someone falling into a mine or a well, the penalty (compensation) and blood money (diyah) will not be upon the owner of the animal, mine, or well. This is because the owner had employed the worker for the purpose of work, not with the intention of causing him harm. Furthermore, this hadith contains the ruling that upon finding a buried treasure, one-fifth of it must be given as zakat. For details, see (Fath al-Bari: 3/365).
