Is the non-direct participant (Rad') in an aggressive robbery liable if the direct perpetrator is a child or insane person?

Primary text

If the direct perpetrator of the homicide and theft is a child or insane person, no liability for the Hadd of aggressive robbery is imposed upon the accomplice ('Rad' or supporting individual). This is because the ruling of aggressive robbery (Hirabah) is not established against the direct perpetrator due to their lack of accountability. Since the ruling is not established against the principal actor, it consequently cannot be established against the supporting actor who follows by way of dependence.
