We are invited to a family reunion where several families will be staying in one large house with many bedrooms in Florida for a few days. My daughter and i do hijab but most of the other ladies do not (most of the ladies are my mother in law and my brother in laws’ wives and their female cousins. Can my husband go in that gathering as these ladies are from his brother’s in laws and his brother is his big brother so he has a certain fear and respect of him?

They are na mahram for him
