The tradition mentioned above has also been narrated by Ibn Umar through a different chain of transmitters to the same effect as mentioned by Malik. In this version there is no mention of the words "otherwise he will be emancipated to the extent of the first man's share. " His version ends "and the slave be thus emancipated, " to the same effect as he (Malik) mentioned.

1؎: The summary of all the narrations from Abu Hurairah and Ibn ‘Umar (radi Allahu anhuma) is that if someone frees his share from a jointly owned slave and he is wealthy, then he must pay the value of the remaining share to his partner, and the slave will become completely free. Otherwise, the slave should be made to work, without compulsion, to earn the remaining amount, and when even this is not possible, then the remaining share will continue to belong to the other owner, and the slave will continue to serve his other master in proportion to that share. In this sense, there is no difference in the narrations (Fath al-Bari).
