What is the ruling of Islamic law regarding someone who divides his wealth among his daughters during his lifetime so as to deprive other heirs of inheritance after his death?

If a father bequeaths his money to his daughters, and they do not take possession of it until after his death, the gift (hibah) is invalid according to the majority of scholars, unless the adult heirs consent to it. However, if he divides his wealth among them and transfers ownership to them during his lifetime, such that they take possession of it and dispose of it, this is not permissible if he has other male or female children, due to the prohibition of favoring some children over others in a gift. If the heirs are not his children and the donor is someone whose charitable donation is permissible, then the gift is valid whether the heirs consent or not, unless his intention was to deprive some heirs.
