question #3 Sahih al-Bukhari 5750, Book 76, Hadith 65 : 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 Lord of the people! Remove the difficulty and bring about healing as You are the
Healer. There is no healing but Your Healing, a healing that will leave no ailment.”
