Musannaf Ibn Abi Shaybah

Hazrat Sakhr bin Juwairiyah narrates that Hazrat Nafi’ said: During the time of Hazrat Ibn Zubair, there was a madman who would sometimes recover so that he had no ailment, and sometimes his illness would return. During this period, while he was sleeping with his cousin, he entered the room with a dagger and stabbed his cousin in the stomach, killing him. Upon this, Hazrat Abdullah bin Zubair, as a judgment, confiscated all his wealth and gave it to the family of the murdered person.
