Musnad Ahmad 329:40

Ali ibn Ishaq narrated to us, he said: Abdullah and Attab informed us, they said: Abdullah—meaning Ibn al-Mubarak—narrated to us, he said: Ibn Lahi'ah informed us, he said: Habban ibn Wasi' narrated to us, from his father, from Abdullah ibn Zayd ibn Asim al-Mazini, who said: "I saw the Messenger of Allah (peace and blessings of Allah be upon him) performing ablution at al-Juhfah." He then mentioned the meaning of a Hasan (sound) hadith, except that he said: "And he wiped his head with water other than the remainder of his hand."
