Musannaf Ibn Abi Shayba 18:626

Abu Bakr narrated to us, he said: Sulayman ibn Hayyan narrated to us, from Awf, he said: I heard an old man before the sedition of Ibn al-Ash'ath, and he described his description. They said: "That is Abu al-Muhallab, the uncle of Abu Qilabah." He said: A man threw a stone at a man's head, so his hearing, his tongue, his intellect, and his virility departed, and he could no longer approach women. So Umar judged regarding him with four blood-monies.
