"In the year 44 H. (664. A.D.), and in the days of the Khalif Mu’awiya, Muhallab, son of Abu Safra made war upon the same frontier, and advanced as far as Banna and Alahwar, which lie between Multan and Kabul. The enemy opposed him and killed him and his followers. In the land of Kikan, Muhallab encountered eighteen Turki horsemen, riding crop-tailed horses. They fought well but were all slain. Muhallab said, “How much more active than we those barbarians were.” So he docked the tails of his horses, and was the first among the Musulmans who did so."
