Abdul 'Aziz bin al-Mukhtar عبد العزيز بن المختار · The Book of Manumission of Slaves

A man who had no other property emancipated six slaves of his at the time of the death. When the Prophet (ﷺ) was informed about it, he spoke severely of him. He then called them, divided them into three sections, cast lots among them, and emancipated two and kept four in slavery.
