Is zakat obligatory on gold prepared for three daughters, knowing that no one is guaranteed life from death?

Zakat is obligatory on gold if it reaches the threshold of 85 grams and a full lunar year has passed, whether it is owned by the daughters or still in the father's possession, even if it is saved for future marriage needs. This is because Zakat is due on it as long as it is hoarded for accumulation, and the majority of scholars have definitively stated this.
