Are the two blows that appeared on my face, along with its redness, vomiting, and dizziness, revenge from the devils because of the Ruqyah (Islamic exorcism), even though I am diligent in [performing] the protective measures (Tahsinat)?

The harm that afflicts a Muslim from devils may be a known matter, and the jinn may dominate humans with or without a reason. Whoever is exposed to that should be pious, patient, ask Allah for help, and fortify themselves with the prescribed adhkar (remembrances) and recitation of the Qur'an, especially Surat Al-Baqarah. One should not occupy their mind with excessive thoughts about the jinn's revenge and domination, lest it invite obsessive thoughts. What happened may also be due to an organic or psychological cause that requires consulting a doctor.
