Musannaf Ibn Abi Shaybah

It is narrated from Ibrahim that a man gave his slave permission to trade, then the slave became indebted, and the master also died in such a state that the master was in debt. He said: The master's debt will be given precedence over the slave's debt. Al-Bati said: I was not surprised by this: the slave's debt will be given precedence over the master's debt, because he had given him absolute freedom.
