Chapter 12: One who frees his share in a slave
He who emancipates his portion in a slave, full emancipation may be secured for him out of his property (if he has money) if he has enough property to meet (the required expenses), but if he has not enough property, the slave should be put to extra labour (in order to earn money for buying his freedom), but he should not be overburdened.
" He will be required to work (in order to secure freedom) for that por- tion in which he has not been emancipated, without overburdening him."
'Imran b. Husain reported that a person who had no other property emancipated six slaves of his at the time of his death. Allah's Messenger (ﷺ) called for them and divided them into three sections, cast lots amongst them, and set two free and kept four in slavery; and he (the Holy Prophet) spoke severely of him.
" A person from among the Ansar willed away the freedom of six slaves of his at the time of his death."
This hadith has been reported on the authority of Imran b. Husain through another chain of narrators.
Chapter 13: Permissibility of selling a Mudabbar
Who will buy him from me? And Nu'aim b. al-Nahham bought him for eight hundred dirhams and he handed them over to him, 'Amr (one of the narrators) said: I heard Jabir b. 'Abdullah as saying: He was a Coptic slave, and he died in the first year (of the Caliphate of 'Abdullah b. Zubair).
A person amongst the Ansar who had no other property declared a slave free after his death. Allah's Messenger (ﷺ) sold him, and Ibn al-Nahham bought him and he was a Coptic slave (who) died in the first year of the Caliphate of Ibn Zubair.
A hadith like this has been narrated on the authority of Jabir through another chain of transmitters.
