Am I sinful for abandoning a girl possessed by jinn—who fears her secret being revealed—suffering from possession, knowing that I advised her to look into ruqyah websites?

"It is recommended to use Ruqyah (Islamic exorcism/healing), supplication (Du'a), and divine remedies. It is prescribed for a Muslim to perform Ruqyah on themselves because it may be more beneficial than someone else performing it, especially if it is the supplication of one in distress, offered with sincerity and devotion. There is no sin in not disclosing the matter since she is of sound mind. It is permissible to leave the afflicted person without Ruqyah or treatment if they are able to endure the affliction, seeking reward from Allah, as indicated by the hadith of the epileptic woman. This hadith shows that patience in the face of affliction leads to Paradise, and it is permissible to forgo medical treatment, and that supplication is more beneficial than medication."
