Sent by the Umayyad Caliphate's governor of Khurasan, an Arab relief force under al-Musayyab ibn Bishr al-Riyahi managed to break the siege and escort the garrison to safety in Samarkand.

[3][4] The loyalties of Transoxiana's native Iranian and Turkic populations and those of autonomous local rulers remained questionable, however, as demonstrated in 719, when the Transoxianian princes sent a petition to the Chinese and their Türgesh vassals for military aid against the Caliphate's governors.

[1][12] Fearing that reinforcements from Samarkand would not arrive in time, the garrison of Qasr al-Bahili proposed to buy peace for 40,000 silver dirhams, as well as giving seventeen of their own men as hostages to Kursul until the tribute was paid.

[17] According to an eyewitness who was in the fortress, "when the two armies engaged in battle, we thought that the Day of Resurrection had arrived on account of what we heard, namely, the groans emitted by the soldiers, the clashing of iron, and the neighing of the horses.

Al-Harashi quickly seized the initiative, defeated the rebels at Samarkand, and proceeded to restore Muslim rule almost to what it had been during the time of Qutayba, except for the Ferghana Valley, effective control over which was lost.

[9][21] Nevertheless, in 724 al-Harashi's successor Muslim ibn Sa'id al-Kilabi and his army suffered a heavy defeat (the so-called "Day of Thirst") at the hands of the Türgesh when he tried to subdue Ferghana.

Transoxiana thereafter remained contested, and the Arabs did not recover their previous position until the campaigns of the Umayyad governor Nasr ibn Sayyar in 739–741, who took advantage of the collapse of the Türgesh khaganate into civil wars after Suluk's murder in 738.
