Medicine
Bukhari :: Book 7 :: Volume 71 :: Hadith 638
Narrated 'Abdul 'Aziz:
Thabit and I went to Anas bin Malik. Thabit said, "O Abu Hamza! I am sick." On that Anas said, "Shall I treat you with the Ruqya of Allah's Apostle?" Thabit said, "Yes," Anas recited, "O Allah! The Lord of the people, the Remover of trouble! (Please) cure (Heal) (this patient), for You are the Healer. None brings about healing but You; a healing that will leave behind no ailment."
