Note 136 — Chapter VII · Kutayba’s Last Campaigns

Welīd had been most anxious to make his own son heir-apparent in the place of his brother, and in his designs had been supported by Hajjāj and Kutayba. Hence the bad blood that existed between the conqueror and the new Caliph.

Vambéry adds the following details without reference (not to be found either in Tabari or Narshakhi): “Having conquered Farghāna, he went through the Terek Pass into Eastern Turkestān. Here he encountered the princes of the Uïgurs, who in default of union among themselves were easily conquered. We are told that the Arabs extended their incursions into the province of Kansu.... Turfan, on the very first appearance of the Arabs, embraced Islam.” (Bokhara, pp. 31, 32).
