H 318 - It is narrated from Abu Nasr Hibtullah bin Muhammad bin Ahmad Katib Ibn binte Abu Ja’far Amri (q.s.) from his teachers that

He was ordered to be the caretaker in superficies, and superficies cannot be rejected, but through the rejection of the reality of things because of their appearances.
