How can one deal with a son who has dropped out of school, whose behavior has changed towards isolation, staying out late, and not performing prayers, and who is believed to be affected by sorcery? What is the jurisprudential explanation for this situation that has caused psychological distress to the mother, and is there any validity to the mother's feelings of guilt?

We ask Allah to grant you guidance, faith, and well-being. We do not have an explanation for what is happening to your brother, but we advise you to continue counseling him, performing Ruqyah (definition) (Islamic exorcism) on him according to the Sharia (definition), keeping him away from bad company, and encouraging him to associate with righteous companions.
