Musnad Abu Ya'la al-Mawsili 130:30

Ja'far ibn Mihran narrated to us, 'Abd al-Warith narrated to us, from 'Abd al-'Aziz, who said: I and Thabit entered upon Anas. Thabit said to him, "O Abu Hamzah, I have become ill." Anas ibn Malik said to him, "Shall I not perform *ruqyah* (incantation) upon you with the *ruqyah* of Abu al-Qasim (may Allah bless him and grant him peace)?" He said, "Yes." "O Allah, Lord of the people, remove the affliction, heal, for You are the Healer. There is no healer but You, a healing that leaves behind no sickness."
