Malik said, "When a mukatab who fulfils his kitaba and becomes free dies, he is inherited from by the people who wrote his kitaba and their children and paternal relations - whoever is most deserving."
He said, "This is also for whoever is set free when he dies after being set free - his inheritance is for the nearest people to him of children or paternal relations who inherit by means of the wala'."
Malik said, "Brothers, written together in the same kitaba, are in the same position as children to each other when none of them have children written in the kitaba or born in the kitaba. When one of them dies and leaves property, he pays for them all that is against them of their kitaba and sets them free. The money left over after that goes to his children rather than his brothers."
