Chapter on the Contract of Manumission (Mukataba)

Imam Jafar ibn Muhammad Al-Sadiq عليه السلام was asked about a mukatab (a slave under a contract of emancipation) who was unable to complete the payments of his contract, although he had already paid part of it. Imam عليه السلام said: "The remaining amount should be paid on his behalf from the charity funds, as Allah سبحانه وتعالى, the Mighty and Majestic, says in His سبحانه وتعالى Book: 'and for freeing slaves' (Surah At-Tawbah 9:60)."
