Is eating mushrooms permissible in Islamic law?

Mushrooms (fungi) are plants that grow above ground. Their types vary; some are poisonous, while others are beneficial and edible, possessing numerous health benefits such as treating anemia, being cholesterol-free and fat-free, and serving as a nutritional supplement rich in protein and vitamins. The fundamental principle regarding foods and drinks is permissibility, unless something is proven to be forbidden. Therefore, it is permissible to consume beneficial and safe types of mushrooms, while it is forbidden to consume poisonous or harmful types, based on the general prophetic saying: "There should be no harm nor reciprocating harm," and because Islamic law protects bodies.
