What is the legal right, according to Sharia, of the wife and her five daughters to the deceased husband's house, given the presence of other heirs, and is the house legally the right of the wife alone, especially since the state transferred its ownership to her?

The deceased's wife and daughters do not have the right to claim sole possession of the house, excluding the other heirs. If a man dies, leaving behind a wife, daughters, a father, and a mother, then these are his only heirs. The wife receives one-eighth of the house, the five daughters receive two-thirds of the house, the mother receives one-sixth of the house, and the father receives one-sixth of the house. This is a 'A'ilah (a share distribution where the sum of the prescribed shares exceeds the total inheritance) case, so it is divided into 135 shares: the wife receives 15 shares, the daughters receive 80 shares (16 for each), the mother receives 20 shares, and the father receives 20 shares. It is not permissible for the wife to deprive the other heirs of their right based on man-made laws; otherwise, she would be unjust and transgressing the bounds set by Allah.
