Chapter on Kitāba (Contractual Manumission)
Kitāba is the master’s sale of his slave to himself for a lawful, specified sum that becomes a debt upon the slave, a commodity for which salam is permissible, payable in two or more instalments, each instalment’s amount and due date being clearly known. No single final deadline for the whole amount is required, and the sum must lie within the slave’s capacity to earn. If any one of these conditions is absent, the contract is invalid.
Whether concluded while the master is healthy or ill, the liability created by kitāba is charged against the principal estate.
It is effected only through an explicit verbal declaration4 by someone with full legal capacity; nonetheless, if the contract is made with a discerning minor slave, it is valid.
Once the mukatab has paid the entire amount he owes—or the master has waived it—he is emancipated, and whatever surplus remains in his possession belongs to him.
