Musannaf Ibn Abi Shaybah 36099 — Reports on Tustar

Shuways al-Adawi said: I took part in the battle of Maysan. I took a slave girl captive and married her. Then a letter from Sayyiduna Umar (may Allah be pleased with him) came to us, in which he had written: "Return the captives of Maysan." So I returned that slave girl, and I do not know whether she was pregnant or not. This was the cause of greater prosperity for their settlements and of a greater collection of land tax.
