Narrated to me Abu al-Tahir: Ibn Wahb informed us: Mu'awiyah ibn Salih informed me, from 'Abd al-Rahman ibn Jubayr, from his father, from 'Awf ibn Malik al-Ashja'i, who said: "We used to practice ruqyah (incantation) in the pre-Islamic period of ignorance. So we said, 'O Messenger of Allah, what is your view on that?' He said, 'Present your ruqyah to me. There is no harm in ruqyah as long as it does not contain shirk (association of partners with Allah).'"
