Sayyiduna Abu Hurairah (may Allah be pleased with him) narrated from the Messenger of Allah (peace and blessings be upon him), he (peace be upon him) said: "Whoever frees his share in a jointly owned slave, it is obligatory upon him that if he has wealth, he should grant the slave complete freedom from his own wealth. And if he does not have wealth, then the value of the slave should be assessed justly, then regarding the share which has not been freed, the slave should be told to strive to earn and obtain his freedom himself, but no hardship should be imposed upon him."
