What is the ruling of the Sharia on depositing money in the Egyptian Post Authority, and is Zakat obligatory on this deposited money, and what is the ruling on gold that is purchased for the wife and its owner has not been determined, and is Zakat obligatory on it if it is distributed between the wife and daughters?

It is not permissible to save money in the post office or banks that guarantee capital and give a percentage of profits. It is permissible to pay Zakat (definition) in advance before the completion of the year, according to the majority of scholars. Gold jewelry prepared for personal use is not subject to Zakat, according to the majority of scholars, unlike that intended for saving or trade. It is preferable to pay its Zakat to avoid disagreement. If a man buys gold for his wife to sell when needed, then Zakat is due on it because it is intended for saving. If the gold reaches the nisab (definition), Zakat becomes obligatory on it, whether half of it is for his daughters or for him.
