Sourcing, its chain is daif. Ibn Majah narrated it in the Book of Business Transactions, chapter on the guarantee for slaves, hadith 2245, from Hasan Basri, with this wording. Munziri said, this is disconnected, for it is not established that Hasan heard from Uqbah. There is another route for it, which is daif, found in Ibn Majah, hadith 2244.
