Narrated Kharija b. as-Salt quoted his paternal uncle as saying:
We came to a clan of the Arabs after leaving God's Messenger and they said, “We have been told that you have brought what is good from this man. Have you any medicine, or a charm, for we have a lunatic in chains?" When we replied that we had, they brought a lunatic in chains and I recited Fatihat al-Kitab over him three days morning and evening, collecting my saliva and then spitting it out, and he seemed as if he were set free from a bond. They gave me some payment, but I refused to accept it till I had asked the Prophet. When I did so he said, “Accept it*, for by my life, some accept it for a worthless charm, but you have done so for a genuine one."
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 God’s Book.” When they came to Medina and told God’s Messenger that he had taken payment for God's Book, he replied, “The most worthy thing for which you have taken payment is God’s Book."
Bukhari transmitted it. In a version he said, “You have done right. Divide them and give me a share along with you."
Narrated He reported God’s Messenger as saying that God most high has said, “There are three whose adversary I shall be on the day of resurrection:
a man who gave a promise in my name then acted faithlessly; a man who sold a free man and enjoyed the price he received for him; and a man who hired a servant and, after receiving full service from him, did not give him his wages.”
