al-Laith bin Sa'd الليث بن سعد · Medicine (Kitab Al-Tibb)

I had a pain which was about to destroy me. So the Prophet (ﷺ) said : Wipe it with your right hand seven times and say : “I seek refuge in the dominance of Allah, and His might from the evil of what I find.” Then I did it. Allah removed (the pain) that I had, and I kept on suggesting it to my family and to others.
