Does the Prophetic Hadith prohibiting favoritism among children apply to married daughters who are now demanding their rights to real estate that their father registered in the name of some of their male siblings, knowing that these siblings paid off the father's debts and covered the questioner's marriage and education expenses?

Justice must be observed between sons and daughters in inheritance and gifts. The estate must be divided according to what Allah the Almighty has ordained in His Book: "For the male, what is equal to the share of two females." It is not permissible to deprive a female of her share due to marriage, as marriage does not preclude inheritance. Such traditions are invalid. All daughters, whether married or unmarried, are partners in the inheritance, and each is given her right. However, if a mature, sensible woman waives her right for the benefit of an unmarried sibling, there is no harm in that.
