What is the Shar'i (Islamic legal) ruling on a wife living alone in her husband's family home with his brothers and father, and is it better for her to stay in her family's home until her husband travels?

You must obey your husband by remaining in your independent lodging within his family's house, so long as you are not subjected to harm. However, it is better for him to permit you to stay overnight at your family's home unless there is corruption in doing so. The foundation of the marital relationship is compassion, understanding, and overlooking [faults].
