2. Ali ibn Ibrahim has narrated from his father from Ibn Abi ‘Umayr from certain persons of his people who has narrated the following: “About the case of a man who made a contract with his slave and a condition that his legacy will be for him, which then was brought before ’Amir al-Mu’minin , who annulled his condition saying that the condition of Allah is before your (the master’s) condition.’”
