What is the effective treatment for a committed person who has been suffering from sorcery and jinn in his body for 15 years, and has undergone Ruqyah Sharia for three years without success?

The world of the Jinn is unseen (ghayb); no one knows their conditions except within the limits of the sacred texts. Trials and calamities do not necessarily indicate a deficiency in worship, as the Messenger of Allah, Ayub (Job), peace be upon him, was afflicted and endured patiently. Legitimate ruqyah (incantation) may not be effective due to the reciter or the one seeking recitation. Furthermore, the lack of healing might be a benefit for the patient and a reward for them in the Hereafter. It is advisable to turn to Allah Almighty and supplicate to Him, for He removes distress and answers the distressed.
