Islam in Cold War era Soviet Union

The main reason for Russia to invade Afghanistan in 1979 was due to the request of Nur Muhammad Taraki, in order to prop up his Communist regime. However, I am curious to know, did the threat of extremist Islam, which was growing roots in Afghanistan at that time, influence the decision of the Soviets to invade Afghanistan? Since the Soviet Union at that time was very atheist, did the threat of Islam play a part in the decision?
