Musnad Ahmad 31:567

Muhammad ibn Abd al-Rahman al-Tafawi narrated to us, Dawud narrated to us, from Abu Nadra, from Abu Sa’id al-Khudri, who said: "The Messenger of Allah (peace and blessings of Allah be upon him) fell ill, so Gabriel came to him and performed ruqyah upon him. He said: 'In the name of Allah, I perform ruqyah upon you, from everything that harms you, from every eye or envious person, may He heal you,' or he said: 'May Allah heal you.'"
