What is the ruling on Zakat for gold gifted to a wife, knowing that Zakat was not paid on it for more than twenty years before it came into her possession?

If a Muslim owns a nisab (definition) (minimum taxable amount) of gold (85 grams) and a hawl (full lunar year) passes while it is in their possession, zakat (definition) (alms) of 2.5% becomes obligatory on it. This includes women's jewelry intended for adornment, according to the more preponderant opinion. Whoever has not paid zakat for years must pay it for all past years, whether they were aware of its obligation or not, unless the ignorance pertained to the obligation of zakat on jewelry. In this case, they are not required to pay zakat for the past due to the strong jurisprudential disagreement on the issue.
