Musannaf Ibn Abi Shaybah 10822 — Wealth whose zakah is paid is not

Sayyiduna Ibn Umar (may Allah be pleased with them both) says: After a man died, ten thousand dirhams of his were found as (buried) treasure. People said: "This is treasure on which zakah was not paid." Sayyiduna Ibn Umar (may Allah be pleased with them both) said: "Perhaps he used to pay its zakah from other wealth."
