Maliks Muwatta Book 039, Hadith Number 002.

Section : Judgement on the Mukatab.

Malik related to me that he had heard that Urwa ibn az-Zubayr and Sulayman ibn Yasar said, "The mukatab is a slave as long as any of his kitaba remains to be paid."

Malik said, "This is my opinion as well."

Malik said, "If a mukatab dies and leaves more property than what remains to be paid of his kitaba and he has children who were born during the time of his kitaba or whose kitaba has been written as well, they inherit any property that remains after the kitaba has been paid."
