Is it permissible to allocate a sum of money for daughters for future marriage expenses, and are jewelry, housing, and a car considered part of the general inheritance, or are they designated for the wife and daughters?

It is permissible for a father to gift his daughters something from his wealth if he is fair between them and relinquishes control over the wealth, such that each of them takes legal possession of it, enabling her to dispose of it. However, if the gift is contingent upon his death, it is a bequest to an heir, which is not permissible unless approved by the other heirs. The jewelry that the father bought for his wife, gifted to her, and she took possession of, became her property. It is considered part of her estate after her death and is to be divided among her legal heirs. The customary practice of bequeathing a woman's jewelry to her daughters only is invalid, and all of the father's possessions devolve to all his heirs after his death according to their legal shares.
