2. A number of our people have narrated from Sahl ibn Ziyad and Ahmad ibn Muhammad all from ibn Mahbub from al-‘Ala’ from Muhammad ibn Muslim who has said the following: “I once asked one of the two Imam, (abu Ja’far or abu ‘Abd Allah), ‘Alayhim al-Salam, about the case of a man who sells a slave and finds out that the slave owns assets. He (the Imam) said, ‘Such assets belong to the seller; he has sold the slave’s person unless it is a condition in the contract of sale that says that whatever assets are there, they belong to him.’”
