Son of a poor peasant, he was born in a village of the Qakh region in Azerbaijan.
In 1928 he graduated from the Zaqatala Agricultural Technical School and in 1932 - the Institute of Agriculture of Azerbaijan (now Azerbaijan State Economic University).
Since then he has conducted scientific research works. In 1940, he joined the Azerbaijan Communist Party and received many important encharges. In 1954, he was elected the First Secretary of Azerbaijan Communist Party.
In 1956 together with the then chairman of the Supreme Soviet of the Azerbaijan Soviet Socialist Republic, Mirza Ibrahimov, he was able to introduce a new paragraph to the constitution of the Azerbaijan Soviet Socialist Republic that for the first time since the Soviet invasion declared Azerbaijani language the official language of the Azerbaijan Soviet Socialist Republic. As a result of this step which was not agreed upon with Moscow (out of fears of it getting refused) Azerbaijani acquired increasingly an important status in the entire country.
This was the main reason behind his premature removal from power. After being removed from that office, he worked as the Director of Azerbaijan National Academy of Sciences.
Mustafayev was implicitly accused of nationalism, and on June 12, 1959, he was fired for "not being able to cope with his work" and was expelled from membership of the bureau of the Azerbaijan Communist Party Central Committee.
