Sahih Muslim

If anyone emancipates his share ina slave and has enough money to pay the full price for him, a fair price for the slave should be fixed, his partners given their shares, and the slave be thus emancipated, otherwise he is emancipated only to the extent of the first man's share.

This hadith has been reported on the authority of Ibn 'Umar through another chain of transmitters.

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.

" If he (one of the joint owners emancipating the slave) has not (enough) money (to secure freedom for the other half) a fair price for the slave should be fixed, and he will be required to work to pay for his freedom, but must not be over-burdened.

A hadith like this is reported on the authority of the same chain of transmitters but with a slight change of words.

We are prepared to sell her to you on the condition that her right of inheritance would vest with you. She (Hadrat A'isha) made a mention of that to Allah's Messenger (ﷺ) whereupon he said: This should not stand in your way. The right of inheritance vests in one who emancipates.
