Qutayba ibn Muslim
Kashgar, Samarkand, Bukhara and Paikent fell to Qutayba ibn Muslim. In response, the Arabs were almost beaten back by the Turgesh, who were partners with the Sogdians. Sulaiman most likely executed Qutayba, who, after seizing Samarkand and Bukhara, had crushed Sassanian remnants and had Khorezmian scholars slaughtered. Ferghana, Khojand and Chach had fallen to Qutayba.
