Issues:

The first: If a person finds buried treasure bearing no sign of non-Muslim origin, nor any indication that it dates back to the pre-Islamic period, then, if its owner is known, it must be returned to him or he must be informed of it. That is, either you carry it to its owner or notify him of it. Notification is easier in this case, since it may be heavy and require transport; once you have informed him, you have discharged your responsibility.

If its owner is unknown—such that no name is found on it and there is no reason to suppose that it belongs to a particular person—then it is treated as lost property: it must be publicly announced for a full year. If its owner comes forward, it is returned to him; otherwise, it belongs to the finder.

The second: If you hire a man to dig a well in your house or elsewhere, and he finds this buried treasure, then the matter requires further detail:

If the landowner hired this worker to extract the buried treasure, it belongs to the owner of the house. But if he hired him merely to dig, and the worker finds it, then it belongs to the worker, owing to the Prophet’s statement: “Actions are only by intentions, and each person shall have only what he intended.” (1)

The third: The Prophet’s statement, “When you assess the yield, take [the zakah due] and leave one-third; if you do not leave one-third, then leave one-quarter.” (2)—does this mean that zakah is waived on this
