If one because of eating clay loses his power that he had before eating clay and fails to work as he did before eating clay he will be made to suffer proportionate to the amount of power that he had lost because of eating clay.’” جهول - Allamah Baqir al-Majlisi (Mirʾāt al-ʿUqūl fī Sharḥ Akhbār Āl al-Rasūl (2/64))
