What is the method for paying zakat on money collected from associations, on a debt that was outstanding for a year and then recovered, and on gold that has been held for two and a half years?

Zakat becomes obligatory on money if two conditions are met: reaching the nisab (which is equivalent to 85 grams of gold or 595 grams of silver), and the completion of a full lunar year (hawl). So, if the wealth reaches the nisab and remains for a full lunar year, zakat becomes obligatory on it, and its amount is 2.5%. However, if it does not reach the nisab or a full year has not passed on it, then no zakat is due on it.
