Abu Hurairah · The Book of Emancipating Slaves

The slave who is jointly owned by two persons, and is emancipated by one of them, (this one) has liability (upon him to secure complete freedom for that slave).

If anyone emancipates a share in a slave, he is to be completely emancipated if he has money; but if he has none, the slave will be required to work to pay for his freedom, but must not be over-burhened.

'A'isha (Allah be pleated with her) thought of buying a slave-girl and emancipating her, but her owners refused to (sell her but on the condition) that the right of inheritance would vest in them. She made a mention of that to Allah's Messenger (ﷺ). whereupon he said: Let this (condition) not stand in your way for the right of inheritance vests with one who emancipates.

He who takes anyone as his ally without the consent of his previous master, there will be the curse of Allah and that of His angels upon him, and neither, any obligatory act of his nor the supererogatory one will be accepted (by Allah).

He who took the freed slave as his ally without the consent of his previous master, there is upon him the curse of Allah and that of His angels and that of the whole mankind, and there will not be accepted from him his obligatory acts or supercrogatory acts on the Day of Resurrection. This hadith is narrated through the same chain of transmitters, but with a slight change of words.

If anyone emancipates a Muslim slave, Allah will set free from Hell an organ of his body for every organ of his (slave's) body.

He who emancipates a slave, Allah will set free from Hell every limb (of his body) for every limb of his (slave's) body, even his private parts.

I heard Allah's Messenger (ﷺ) as saying: He who emancipates a believing slave. Allah will set free from Fire his every limb for every limb of his (slave's), even his private parts for his.

A Muslim who emancipates a Muslim (slave). Allah will save from Fire every limb of his for every limb (of the slave). Sa'id b. Marjana said: When I heard this hadith from Abu Huraira (Allah be pleased with him), I went away and made a mention of it to 'Ali b. Husain and he at once emancipated the slave for which Ibn ja'far was prepared to pay ten thousand dirhams or one thousand dinars.

A son does not repay what he owes his father unless he buys him (the father) in case he is a slave and then emancipates him. In the narration transmitted by Ibn Abu Shaiba there is a slight change of words.
