What is the legal ruling on wearing a ring made from the Kook tree, and is it true that it cures illnesses and treats sorcery?

The default ruling is that it is permissible to wear a ring made of anything except gold for men. However, wearing a ring made from a specific tree with the belief that it repels or removes harm makes it an amulet. The Sacred Law has indicated the prohibition of amulets and that they constitute polytheism (shirk). Thus, whoever wears an amulet has committed shirk.

The reasons why wearing an amulet is considered shirk: If the wearer believes that it, by itself, cures or protects: This is major shirk in Tawhid al-Rububiyyah (Oneness of Lordship), because he has associated a partner with Allah in governance. If he believes that it is a means but not an active agent by itself: This is minor shirk, because he has adopted a means that Allah has not made a means.

This applies to the statement that a ring made from that tree cures diseases or magic: If the one who says this believes that the ring itself performs this act: This is major shirk; because the Healer is Allah the Almighty. If he believes that the ring is a means and not an active agent by itself: This is minor shirk, as he has adopted a means that Allah the Almighty has not made a means.

Therefore, it is not permissible to wear the ring with that belief. And if wearing it with such a belief is widespread, then it should not be worn even without the belief, especially by people of knowledge and virtue, to prevent joining those who promote superstitions and deceive people.
