Malik said, "The generally agreed on way of doing things among us is that when slaves write their kitaba together in one kitaba, and some are responsible for others, and they are not reduced anything by the death of one of the responsible ones, and then one of them says, I cant do it, and gives up, his companions can use him in whatever work he can do and they help each other with that in their kitaba until they are freed, if they are freed, or remain slaves if they remain slaves."
