Ibn 'Abbas said some of the Prophet's companions passed a watering-place where there was one who had been stung by a scorpion or bitten by a snake. One of the inhabitants of the watering-place accosted them and asked whether anyone among them could apply a charm, for at the watering-place there was a man who had been stung by a scorpion or bitten by a snake. One of them went and recited Fatihat al-Kitab in return for some sheep, and he was cured; but when he brought the sheep to his companions they disapproved of that saying, “You have taken payment for Allah’s Book.” When they came to Medina and told Allah's Messenger ﷺ that he had taken payment for Allah's Book, he replied, “The most worthy thing for which you have taken payment is Allah’s Book." Bukhari transmitted it. In a version he said, “You have done right. Divide them and give me a share along with you."
