Musnad Abu Ya'la al-Mawsili 237:5

Narrated to us Surayj, narrated to us Yahya ibn Zakariyya, from Isma'il, from Qays, who said: I heard Khalid ibn al-Walid speaking to the people in al-Jaridah. He said: "I truly saw myself on the day of Mu'tah, and nine swords were broken in my hand, and there remained with me only a Yemeni blade of mine."
