Musannaf Ibn Abi Shaybah 33755 — One who dies leaving no agnates

Sulayman bin al-Mughirah said: I asked al-Hasan about a man who had a sale transaction with a woman of the Ahl al-Dhimmah. She had something with him; he ended the dealing with her, and then could not find her. Should the man put that thing in the public treasury of the Muslims? He said: Yes.
