Zakah on the delayed deferred allowance

Question:
I retired from my job six years ago, and my deferred allowance was not paid to me monthly during this period. Then I returned to collect it in a single lump sum after six years had passed. Is zakah due on it? And how many times is zakah obligatory on it?

Answer:
Yes, if it was established for you and determined for you, but you were the one who delayed taking possession of it, then zakah is obligatory on it for the past years. For each year, it is one-tenth of the money available to you in the treasury for that year. One-tenth, which is two and a half percent. This is one-tenth. Yes.
As for if it was not determined and not established for you, and you do not know whether it will be established or not, and you are reviewing it but do not know if it will be established or not, then there is no zakah on it until it is established and determined, like a debt owed to a person who is prevented from completing his Hajj, where it is unknown whether it will be obtained or not.
