question #3 Sahih al-Bukhari 5742, Book 76, Hadith 57 : What is the importance of faith in Allah as the ultimate healer in Islamic tradition?

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 Messenger (ﷺ)?” 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.”
