Hazrat Auf narrates that I heard from a certain Sheikh before the Fitnah of Ibn Ash'ath that he described its characteristics. Those people said: This is Abu al-Muhallab, who is the uncle of Hazrat Abu Qilabah. He said that a man struck another man on the head with a stone, causing him to lose his hearing, speech, intellect, and the power of his sexual organ, so that he could no longer approach women. Upon this, Hazrat Umar decided that four blood monies (diyahs) should be given for him.
