Musannaf Ibn Abi Shaybah 23517 — The pledger who pledges a slave

Sufyan said: If a man frees a slave, the slave leaves the pledge; if he makes him a mudabbar, he likewise leaves the pledge; and if it is a slave woman with whom he has intercourse and she bears him a child, she too leaves the pledge. Then, if the master is wealthy, the pledgee shall pursue the master; and if the master is poor, these people (the slave and the slave woman) shall work to earn whichever is less, the value or the pledge. Sufyan said: Then, when the master becomes wealthy, that slave shall claim from his master whatever he worked to earn (that is, he shall recover that much money or value from him), but the umm walad and the mudabbar shall not claim from the master, because their service belongs to the master.
