What is the ruling on living with a woman who prays and does no harm, but commits the sin of talking to a young man and holding hands, and is it permissible to advise her despite her not having responded to advice previously?

A girl's conversation with a foreign young man and their holding hands is a reprehensible act and a pretext for corruption. If a girl is seen in this state, she must be denounced through enjoining good and forbidding evil, according to one's ability, while observing gentleness and a good approach. The advice can be repeated. There is no harm in residing with her as long as no harm is feared, but one must be careful not to be too familiar with her or to sit with her during the sin.
