What is the ruling on the distribution of inheritance that equalizes men and women, cancels the will, and considers the inheritance of a grandson whose father died during his grandfather's lifetime as if his father were still alive?

If equating men and women means giving a daughter a share equal to a son's in inheritance, this contradicts Allah's division, and it is not permissible for a female to take more than her legal share. As for giving a grandchild the share of their father, had he been alive, if it is based on a grandfather's will within the limits of one-third, then it is permissible, because it is a bequest to one who is not an heir. However, if it is without a will, it is not permissible, because it is an inheritance for one who is not an heir, and this is what is known as the invalid compulsory bequest law.
