What are the Sharia-compliant reasons behind the return of family disputes, the loss of money, insomnia, and the inability to study, after seeking help from a spiritual healer who claimed to cure ingested black magic?

Jinn and devils have no power to take money from where it is secured. Marital problems and study difficulties often have tangible and realistic causes, and one should strive to treat them instead of assuming magic. Although magic is real, most of what is claimed to be magic is not. Ruqyah Shariah (Islamic exorcism), traditional invocations and supplications, and reciting Surat Al-Baqarah in the home are recommended for expelling devils.
