الرقية بالفاتحة
Reciting the Qur'an's opening chapter over an unwell person, historically used to treat a scorpion or snake sting, given as an example of permissible spiritual healing.
وَمَا أَدْرَاكَ أَنَّهَا رُقْيَةٌ
“And what made you know that it [al-Fatiha] could serve as ruqyah?” (meaning, not a literal translation)
The full narration describes a companion reciting al-Fatiha over a tribal chief bitten by a scorpion, who recovered; the Prophet ﷺ approved of the practice and the wage received for it.
Ibn al-Qayyim treats ruqyah as a recognized category of Prophetic treatment provided it uses Qur'an, authentic supplication, or comprehensible Arabic — free from ambiguous incantations or anything resembling shirk.
