Abu Sa’īd al-Khudrī said, “Some of the Companions of the Prophet ﷺ went on a journey. They alighted with a certain clan of the Arabs. Someone of them said, “Our chief has been stung by a scorpion or bitten by a snake. Has any of you something which gives relief to our chief?” A man of the people said, “Yes, I swear by Allah. I can recite an incantation, but we asked you for hospitality and you denied it to us. I shall not recite the incantation until you give me some payment.” So, they promised to give some sheep to him. He came to him and recited Sūrah al-Fātiḥah over him and blew (upon him) till he was cured, and he seemed as if he were set free from a bond. So, they gave him the payment that was agreed between them. They said, “Distribute it.” The man who applied the treatment said, “Do not do it until we approach the Messenger of Allah ﷺ.” And He ﷺ said, “From where did you learn that it was a treatment? You have done right. Apportion them, and give me a share along with you.” Reference: Sahih al-Bukhari 5007
