Is the gold that the father bought for his daughters considered an inheritance, or not, and what is the ruling on distributing it among the sons and daughters?

If the father does not own gold for his daughters but rather bequeaths it to them, this is a bequest to an heir, which is impermissible unless approved by the rest of the adult, mature heirs. This is based on the Prophet, peace and blessings be upon him, saying: "Indeed, Allah has given every rightful person his right, and there is no bequest to an heir." If the heirs approve it, then it is permissible according to the majority of scholars. However, if he owned it for them and their mother took possession of it on their behalf, then the gift is considered effective if possession occurred before death or during a death-bed illness.
