The obligation of the wife and children of a usurer and their maintenance from him

Question:
Another question: What is the duty of his wife and children, and what do you advise them?

Answer:
It is obligatory for his wife and children to advise him and warn him of Allah (Mighty and Majestic). If they have no source of income except from him, and if they were to leave him they would starve or be lost, they should eat from his maintenance to the extent of dire necessity. This is because these are matters of dire necessity; if they stopped eating from what he provides, they would starve, as they have no other means or source of income. They should eat from it until Allah makes a way out for them, until the children grow up, become independent, go out, earn a living, become self-sufficient, and leave him, taking their mother and sisters with them. As long as they are minors and have no source of income except what their father, who is in this state, gives them, they should eat from it due to dire necessity, and the sin is upon him.
