Musnad Ahmad 75:4

Ibrahim ibn Abi al-Abbas narrated to us, he said: Sharik narrated to us, from Simak ibn Harb, from Muhammad ibn Hatib, who said: I crawled toward a pot while it was boiling, and I put my hand into it, so it was burned—or he said: my hand swelled. My mother took me to a man who was in al-Batha, and he said something and blew [upon it]. When it was during the reign of Uthman, I said to my mother: "Who was that man?" She said: "The Messenger of Allah, may Allah bless him and grant him peace."
