Musannaf Ibn Abi Shaybah 36089 — Reports on Tustar

Sudays al-Adawi said: We took part with our commander in the battle of al-Ubullah. We were victorious there. Then we went to Ahwaz, where there were people of the Zutt and the Asawirah. We fought them fiercely and we were victorious. Many captives fell into our hands, and we divided them among ourselves. Some men got one captive and some two. We also had intercourse with the women we owned. When Sayyiduna Umar (may Allah be pleased with him) was informed of this, he wrote to us a letter in which it was written: "You do not have the capacity to cultivate the land. Free all the captives; you are not to take ownership of any one of them. Take land tax (kharaj) from them in proportion to the land they hold." So when this order came, we freed all the captives. How many a child of ours was overcome by al-Hammas! Among the Zutt whom we had overcome, many resembled the Arabs. They kept long beards, wore waist-wrappers and sat with a cloth wrapped around their legs. Sayyiduna Umar (may Allah be pleased with him) was written to about them, and he said: "Bring these people near you, and whoever of them accepts Islam, join him with the Muslims." When they were tested against people, they proved to have no fighting strength. The Asawirah were stronger than they were. Sayyiduna Umar (may Allah be pleased with him) was written to about them too, and in reply he said: "Bring them near, and whoever accepts Islam, join him with the Muslims."
