Musannaf Ibn Abi Shaybah 11086 — Buried treasure found by a group

Husayn narrates from a man who was present at the Battle of Qadisiyyah, who said: There was a man among us who was bathing; when the water, falling on the ground, dug a hole in it, a brick of gold appeared. That man brought it to Sayyiduna Sa'd bin Abi Waqqas (may Allah be pleased with him) and informed him about it. He said: Include it in the spoils of the Muslims.
