Who is the guardian of an unconscious patient (in a coma), and who comes after him in order of precedence?

Guardianship over an unconscious patient is similar to that over a child or an insane person. It belongs to the son, then the father, then the grandfather, then the brother, then the closest maleagnate (asabah). The patient's or guardian's permission is not required in two situations: First, if the patient is threatened with death or organ damage and their consent cannot be obtained. Second, if the illness is an epidemic and there is fear of its spread.
