The Messenger of Allah ﷺ permitted the use of ruqyah for the evil eye, scorpion stings, and skin sores.
رخص رسول الله ﷺ في الرقية من العين، والحمة، والنملة.
Muslim narrated it in the Book of Greetings (2196: 98) through several routes from Asim al-Ahwal, from Yusuf bin Abdullah, from Anas, and he mentioned it. The namlah is sores that appear on the side of the body.
