What is the ruling on writing over a portion of one's property to daughters, and who are the legitimate heirs?

It is permissible for a mother to gift all or part of her possessions to her daughters, provided there is fairness among them and they take possession of the gift during her lifetime. If they do not take possession of it during her lifetime, the gift is null and void unless ratified by the adult, mature heirs. The five daughters inherit two-thirds as a prescribed share, and the remainder is returned to them, because distant kindred do not inherit when there is an heir with a prescribed share or an agnate.
