What is due in zakat on gold for a deceased woman who did not pay zakat on it during her lifetime, and zakat was paid on it only once after her death, and the gold has not been divided among the heirs?

The deceased's gold: If it was for personal use, there is no zakat on it according to the majority of scholars, and this is the ruling given for fatwas. However, if it was not for personal use, zakat is obligatory for all past years until death. If the number of years is unknown, one should act based on what is most likely.

After death: Ownership of the gold transfers to the heirs. If years passed before the inheritance was distributed, then whoever's share of the gold reached the nisab, either by itself or by combining it with other wealth, zakat becomes obligatory upon them when they receive their share, for each year. The Malikis are of the view that the inherited gold begins a new Hawl (lunar year) for the heir.

The Nisab: 85 grams of gold, and what is obligatory to be given is a quarter of a tenth (2.5%).

The matter should be referred to a Sharia court to consider the inheritance, due to its seriousness and complexity.
