Chapter on the Contract of Manumission (Mukataba)

Commander of the Faithful Imam Ali ibn Abi Talib عليه السلام, ruled regarding a mukatabah (a female slave under a contract of emancipation) who passed away after having paid most of what was required of her and had given birth to a child during her contract. Imam عليه السلام ruled that the child should be freed in proportion to the part of the mother that had been freed and remain in bondage in proportion to the part of the mother that was still in bondage.
