My father has recently passed away. He used to live with my mother-in-law at a house owned by my brother. Where should she observe her Iddah, knowing that she has no Mahrams? If my brother wanted his house back, is she allowed to continue her Iddah at another house? Also, is she entitled to the furniture since most of it was gifted to my father and it isn`t part of her bridal gift (Mahr)?
