What do you mean by Islamic state? Something like in Iran, or something like in Turkey? I'm not sure what your sources are but if you mean something like in Iran it's extremely unlikely to happen in Kazakhstan. Russia taking some land is more likely but Russia would likely prefer better relations with Kazakhstan due to their gas and economic ties, and annexing that land isn't really that important compared to Ukraine.
