Question:
Is it permissible to borrow from a man whose earnings are not created?
Answer:
If you are certain that everything he has is haram (forbidden), then it is not permissible for you to borrow from him. However, if you are not certain and it is merely a suspicion, or if this man has money that is a mix of halal (lawful) and haram, then there is no harm in borrowing from him or eating from his food; because it has not been established that it is from the haram, and the default is that it is permissible. Yes. May Allah reward you with good.
