يزيد بن المهلب
Caliph Walid quickly re-confirmed Qutayba as governor, and even made his province independent from the governor of Iraq, but Qutayba's position was not secure: the Arab army was tired of constant campaigning and was still riven by factional rivalries, while Qutayba himself had alienated the most powerful Arab tribal groups. He was generally popular among the native Iranians, but the leader of the native auxiliaries, Hayyan an-Nabati, had secretly turned against him. Qutayba was completely unaware of the situation however, and began preparations for the campaign of 715, during which he intended to finally capture the Ferghana Valley and complete the subjugation of the Jaxartes valley. His only concern was that his old rival, Yazid ibn al-Muhallab, might be restored to the Caliph's favour after al-Hajjaj's death, and he took few precautions except for removing his family and belongings from Merv to Shash and placing a guard on the Oxus.
