Sayyiduna Abdullah bin Abbas (may Allah be pleased with them both) narrates: The Prophet (peace and blessings be upon him) said: "Whoever frees (his) share in a slave will be liable from his own wealth to (the other partners) for their shares."
Imam al-Bazzar recorded this narration from Ibrahim bin Isma'il bin Yahya, from his father, and both of them are da'if (weak).
