Abd al-Rahman bin al-Aswad narrates from his father: I asked Sayyidah Aishah (may Allah be pleased with her) about ruqyah for the sting of a venomous creature, and she said that the Messenger of Allah (peace and blessings be upon him) "granted permission for ruqyah for the sting of every venomous creature."
