question #3 Sahih al-Bukhari 5743, Book 76, Hadith 58 : What is the significance of acknowledging Allah as the ultimate healer in Islamic teachings?

The Prophet (ﷺ) used to treat some of his wives by passing his right hand over the place of ailment and
used to say, “O Allah, the Lord of the people! Remove the trouble and heal the patient, for You are the
Healer. No healing is of any avail but Yours; healing that will leave behind no ailment.”
