Qutayba ibn Muslim served as the governor of Khorasan and was assigned the mission to expand Islamic rule eastward into Central Asia.
Between 705 and 715, he led systematic campaigns across the Oxus River (Amu Darya), bringing Transoxiana under Umayyad control.
His capture of Bukhara (709) and Samarkand (712) secured key trade routes and introduced Islam to Turkic and Sogdian populations.
He extended the empire's reach to the Ferghana Valley and established a presence on the borders of the Tang Dynasty's territory.
Like Muhammad ibn Qasim, he fell victim to political shifts after the death of Caliph al-Walid I and was killed in a revolt by his own troops who refused to support his challenge to the new Caliph Sulayman.
