The ruling on one who fails to pay the zakah on gold for years

Question:
In his final question, he says: There were ten gold coins that had been held for a year up to a year, and no zakah was paid on them. Is there an expiation required for this? And if there is an expiation, what is its amount?

Answer:
When gold reaches the nisab, which is twenty mithqals, zakah becomes obligatory on it every year. So, this gold that has passed through years while reaching the nisab of twenty mithqals or more requires zakah for the past years, which is one-quarter of one-tenth. You calculate it, sum it up for the past years, and pay it out. This is what is obligatory, along with repentance to Allah for delaying the zakah for the time that has passed. Yes.
