Malik said about a man who had his slave in a kitaba and then the mukatab died and left his umm walad, and there remained for him some of his kitaba to pay and he left what would pay it, "The umm walad is a slave since the mukatab was not freed until he died and he did not leave children that were set free by his paying what remained, so that the umm walad of their father was freed by their being set free."
