It is narrated from Hazrat Abu Huraira (may Allah be pleased with him) that the Holy Prophet (peace and blessings be upon him) said: If a person has a partnership in a slave and he frees his share of the slave, then if he is wealthy, it is his responsibility to pay the full price for the slave's freedom. And if he is not wealthy, then the slave should be made to work in such a way to pay the remaining price that it does not become a burden on him (and after the payment of the remaining price, he will become completely free).
