Musannaf Ibn Abi Shayba 21:376

Muhammad ibn Bishr al-‘Abdi narrated to us, Zakariyya ibn Abi Za’idah narrated to us, Simak narrated to us, from Muhammad ibn Hatib, who said: I reached for a pot of ours, and my hand was burned. My mother took me to a man sitting in the graveyard and said to him, "O Messenger of Allah!" He said, "At your service and at your aid." Then she brought me close to him, and he began to blow [upon my hand] and speak—I do not know what it was. I asked my mother after that what he was saying, and she said: "He was saying: 'Remove the harm, O Lord of the people, and heal, for You are the Healer. There is no healer but You.'"
