📚Tahdhib al-Ahkam, Vol. 2, p. 234

Hisham bin Hakam asked Imam Sadiq (AS): Inform me about what it is permissible to prostrate upon and what it is not permissible to prostrate upon. The Imam replied: Prostration is only permissible on the earth or something that grows from the earth, except for things that are consumed (eaten) or worn (as clothing).

📚Tahdhib, Vol. 2, p. 234

Explanation: According to this narration, prostration can be done on all parts of the earth such as soil, stones, and clods, as well as all plants that grow from the earth like trees and various plants, except for edible plants such as vegetables and fruits, as well as plants used for clothing such as cotton and linen.
