Musnad Ahmad 1153:977

'Affan narrated to us, he said: Hammad narrated to us, from Hisham, from 'Urwah, from 'Aishah, she said: "I used to perform Ruqyah for the Messenger of Allah, may Allah bless him and grant him peace, against the evil eye. I would place my hand on his chest and say: 'Wipe away the affliction, O Lord of the people. In Your hand is the cure; there is no remover of it except You.'"
