Jund al-Urdunn
Qutayba b. Muslim, the conqueror of Transoxiana, preferred not to fight the Zunbils and accepted an offer of a rather minimal tribute from them, calling Sijistan an "ill-omened front". Until the reign of Hisham ibn Abd al-Malik, the Sijistan front had ceased to be volatile as the Arabs had given up on conquering the area and no fighting occurred for a long period. This in turn holding led to Zunbils not even paying a token tribute. The policy began to change under Hisham. Khalid al-Qasri in Iraq appointed Yazid b. al Ghurayf al-Hamdani as Sistan's governor, a Syrian from Jund al-Urdunn, in 725. Yazid resumed the campaign by sending an army under the command of Balal b. Abi Kabsha. They however did not obtain anything from the Zunbils.
