Musannaf Ibn Abi Shaybah 29135 — Loss of reason

Awf said: I heard a certain elder before the tribulation of Ibn al-Ash'ath, and he described his attributes. They said: This is Abu al-Muhallab, the paternal uncle of Abu Qilabah. He said: A man struck another man on the head with a stone, and his hearing, speech, intellect and sexual power were lost, and that man could not go near women. So Sayyiduna Umar (may Allah be pleased with him) ruled four blood moneys in his case.
