'Abdul Rahman bin al-Aswad reported on the authority of his father: I asked 'A'isha about incantation. She said: Allah's Messenger (ﷺ) had granted its sanction to the members of a family of the Ansar for incantation in curing every type of poison.
'A'isha reported that Allah's Messenger (ﷺ) granted sanction to the members of a family of the Ansar for incantation (for removing the effects) of the poison of the scorpion.
Narrated Al-Aswad: I asked `Aisha about treating poisonous stings (a snake-bite or a scorpion sting) with a Ruqya. She said, "The Prophet allowed the treatment of poisonous sting with Ruqya."
Shaykh Abdul Sattar al-Hammad
Hadith Commentary: (1) It is mentioned in the hadith that the Messenger of Allah (sallallahu alayhi wa sallam) forbade incantations (ruqyah), so the people of Amr ibn Hazm came to the Messenger of Allah (sallallahu alayhi wa sallam) and said: O Messenger of Allah! We have an incantation (ruqyah) which we use as a remedy for scorpion stings, and you have forbidden incantations. Then they presented that incantation before the Messenger of Allah (sallallahu alayhi wa sallam), so he said: “There is no harm in it. If a person can benefit another, he should certainly benefit him.” (Sahih Muslim, Book of Medicine, Hadith: 5727 (2199)) Similarly, it is narrated from Jabir (radi Allahu anhu) that the Messenger of Allah (sallallahu alayhi wa sallam) permitted the Banu Amr to use incantations for snake bites. (Sahih Muslim, Book of Medicine, Hadith: 5731 (2199))
(2) In any case, it is permissible to perform incantations (ruqyah) for bites from venomous creatures; there is no fault or harm in it. And Allah knows best.
