What must a father do regarding his depriving his sisters and mother of inheritance, and what are the consequences for his heirs if Allah takes his life, knowing that the females have forgiven him and the mother has passed away?

Every Muslim must know that the distribution of inheritances is Allah's ruling and law. Whoever alters any of Allah's rulings or devises schemes to diminish some rights has transgressed Allah's bounds and exposed themselves to His wrath and punishment. It is not permissible to deprive a woman of her inheritance or to scheme to do so. The duty is to act according to Allah's law in inheritances and other matters, and to beware of anything that contradicts it. Similarly, fairness among children is required in gifts to them, with the male receiving a share equal to that of two females. If the father dies before equalizing among the children, then whoever received preferential treatment must return the gift to the estate, and it must be divided among all heirs according to the Sharia. If some refuse, then the rest must return what exceeded their lawful share and distribute it among the deprived sisters.
