His reign saw raids against
Qocho and
Khotan. He developed water conservancy and transportation near
Kashgar and founded a school, a mosque and a library.
Ibn ul-Athir reported that, in 960, during his reign, 200,000 Turkic people embraced Islam. Samanid proselytizers Abul Hasan Said b. Hatim and Abuzar Ammar at-Tamimi were instrumental in this regard. Musa Baytash temporarily lost
Kashgar to the
King of Khotan, Visa Sura (
尉迟输罗) when the latter attacked the Karakhanid state in 971, achieving a big victory. In addition to women and children, there were elephants among the spoils, which were sent to
Song China as tribute. It is unknown when his reign came to an end. He left only one son,
Ali Arslan Khan. His daughter Büwi Maryam's tomb, located in Beshkerem (伯什克热木乡),
Kashgar, is a holy site for Muslims. == References ==
