Musannaf Ibn Abi Shaybah

Ibn Mubarak narrated to us, from Abu Hamzah al-Sukkari, from Yazid al-Nahwi, from Mujahid, from Abu Hurairah, who said: A woman from Quraysh had a slave boy whom she had set as a manager, then she wanted to make a contract of manumission with him. The Messenger wrote to Abu Hurairah, and said: Make a contract of manumission with him; if he fulfills his contract, then so be it, and if something happens to you, he is free. He said: And I think it was for what he owed to him. (Bayhaqi 314)

It is narrated from Hazrat Ibn Masood that if a person sells the service of his mudabbar slave, then whatever the master has already received will be counted for him, and whatever remains will not be obligatory upon the slave.

It is narrated in a similar way from Hazrat Ibn Masood (may Allah have mercy on him), but with this addition: When your companion dies, then there is nothing left for you.

Hazrat Dawood bin Harees narrates that I was present in the service of Hazrat Shurayh (may Allah have mercy on him), and he gave the verdict in the same manner.

Hasan (may Allah have mercy on him) said: Whatever remains due upon him will also be collected from him.

Hazrat Ibn Sirin (may Allah have mercy on him) said that a mudabbar slave should not be sold except in exchange for his own self.

Hazrat Ibn Sirin (may Allah have mercy on him) disliked the sale of a mudabbar slave, and saw no harm in making a mudabbar slave a mukatab.

Hazrat Ata (may Allah have mercy on him) says that do not sell the service of a mudabbar slave except in exchange for his person (life).
