Fath al-Rabbani

It is narrated from Sayyiduna Abu Sa'id Khudri (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him and his family) sent us, thirty mounted fighters, in a military expedition. We stopped by a tribe of the Arabs and asked them for our right of hospitality, but they refused. It so happened that one of their chiefs was bitten by something poisonous. They came to us and said, "Is there anyone among you who can perform ruqyah (healing incantation) for a bite?" Sayyiduna Abu Sa'id Khudri (may Allah be pleased with him) says: I said, "Yes, I can do it, but I will not perform ruqyah until you give us something." They said, "We will give you thirty sheep." Sayyiduna Abu Sa'id (may Allah be pleased with him) says: I began reciting Surah Al-Fatihah over him, recited it seven times, collected my saliva and then spat on him. Thus, he was cured and they gave us thirty sheep. When we took possession of the sheep, we began to doubt (whether they were lawful for us or not). So we refrained from making any use of them until we could ask the Messenger of Allah (peace and blessings be upon him and his family) about them. When we came to the Noble Prophet (peace and blessings be upon him and his family) and informed him of this, he said: "How did you know that it is a ruqyah? Distribute them and set aside my share as well." In another narration it is stated: "You eat yourself and let us eat with you. How did you know that it is a ruqyah?" I said: "It was simply inspired into my heart."
