The Rashīdī History 154.3

154.3

When they heard of the successes of Muhammad Khwarizm Shah, they sent numerous ambassadors to persuade him to attack the Gur Khan from the west. Kushluk, at the same time, was to attack him from the east, so as to bring him out of the centre [of his dominions]. [The conditions were that] if Sultan Muhammad Khwarizm Shah should be the first to gain a victory, Almaligh, Khotan and Kashghar, which were in Kushluk's kingdom, should be ceded to him ; but if, on the other hand, Kushluk should have the first success, Kara Khitai as far as Finakand should be delivered over to him. These conditions having been agreed upon, a treaty was concluded between them. (Finakand means Shahrukhia.)
