Chapter on the Inheritance of the Mukatab (Contracted Slave)

Asim ibn Humaid narrated from Muhammad ibn Qays from Abu Jafar Imam Muhammad ibn Ali Al-Baqir عليه السلام who said: "The Commander of the Faithful عليه السلام ruled regarding a mukatab (a slave under a contract for freedom) who died and had wealth. Imam Ali ibn Abi Talib عليه السلام said: 'His wealth should be divided in proportion to what part of him had been freed for his heirs, and the portion that was not yet freed should be calculated for his masters who had entered into the contract with him from his wealth.'"
