Malik related to me that he had heard that Urwa ibn az-Zubayr andSulayman ibn Yasar said, "The mukatab is a slave as long as any of hiskitaba remains to be paid."Malik said, "This is my opinionas well."Malik said, "If a mukatab dies and leaves moreproperty than what remains to be paid of his kitaba and he haschildren who were born during the time of his kitaba or whose kitabahas been written as well, they inherit any property that remains afterthe kitaba has been paid."
