Musannaf Ibn Abi Shaybah 10921 — A man whose wealth is gone for years

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)."
