For no Sunnah has come regarding it from him, nor from any of his successors through an authentic chain of transmission. Furthermore, the fundamental principle is the absence of obligation regarding it, and it is not valid to draw an analogy between it and land mines, because ambergris is merely cast forth by the sea and found lying [on the land] upon the earth without exertion. It thus resembles permissible items (mubahat) acquired from the land, such as manna, ginger, and others. As for fish, there is nothing due on them at all, according to all scholars, except for something narrated from Umar ibn Abd al-Aziz, which Abu Ubayd recorded from him. He remarked: "People are not upon this, and I do not know of anyone who acts upon it." That has also been narrated from Ahmad, but the correct view is that there is nothing due upon it, because it is game (sayd), and thus no zakat is obligatory upon it, just as with land game; and because there is neither a textual proof (nass) nor a consensus (ijma) regarding the obligation of zakat upon it, so there is no grounds for making it obligatory.

Section: Solid minerals are owned by virtue of the ownership of the land in which they are located, because they are a part of the components of the earth, just like the soil and fixed stones, unlike buried treasure (rikaz), for it is not from the components of the earth, but rather is something deposited within it.

They brought the document of the land grant (qati'a) which the Messenger of God (peace be upon him) had granted to their father, on a parchment. He said: Umar began to wipe it over his eyes, and he said to his steward: "Look at"
