A man whose wealth is gone for years, then finds it and pays zakah on it

Amr bin Maymun said: Al-Walid bin Abd al-Malik took the wealth of a man from the people of al-Raqqah who was called Abu A'ishah, twenty thousand (dirhams), and put it into the public treasury (bayt al-mal). Then when Umar bin Abd al-Aziz became ruler, his children came to him and brought their grievance before him. He wrote to Maymun: "Give them back their wealth and take the zakah of this year of it. Had it not been dimar wealth (wealth whose return was not hoped for), we would have taken zakah from it for the years that have passed."

It is narrated from Maymun that a man's wealth was taken from him in one of the acts of injustice and ended up in the public treasury (bayt al-mal). When Umar bin Abd al-Aziz became ruler, the matter was raised with him, and Umar wrote: "Give it back to him and take from him the zakah for the years that have passed." Then afterwards he followed it with another letter: "Give him back his wealth, then take from him the zakah of that year, for it was dimar wealth (wealth whose return was not hoped for)."

Al-Hasan said: The zakah of that year is due from him.
