Louw, Maria Elisabeth. Everyday Islam in Post-Soviet Central Asia. Central Asian Studies Series, Vol. 7. New York: Routledge, 2007.

Privratsky, Bruce G. Muslim Turkistan: Kazak Religion and Collective Memory. Richmond UK: Curzon, 2001.

Privratsky's book is a good ethnographic survey of contemporary Islamic practice among Kazakhs in Turkistan, Kazakhstan. It discusses, among other things, Sufism, lines of ancestry traced to the first century of Islam, observance (or non-observance) of the five pillars of Islam, shrine visitations like that of the Yasawi Mausoleum, veneration of ancestors, and healing arts. There are interesting discussions about pre-Islamic influences of contemporary religious practices and what are true Islamic practices.
