Hasani finished primary school and Gazi Isa-bey madrasah (high school) in Skopje. He became a writer and wrote his first Albanian language novel, The Grape Starts to Ripen, in 1957.^[1]

Hasani joined the Yugoslav Partisan resistance movement in 1941, during the war, and the Yugoslav Communist Party in 1942. He found himself in Nazi German captivity in 1944, and spent time in a POW camp near Vienna until the end of World War II. After the war, he attended the Đuro Đaković party school in Belgrade (1950–52). Later, he became leader of the Socialist Union of the Working People mass organization in Kosovo, and was from 1965 to 1967 manager of the Kosovar publishing house Rilindja. From 1971 to 1974, he was the Yugoslav ambassador to Denmark. In 1975 he was elected Deputy Speaker of the Yugoslav Federal Assembly, and remained in that position until he became the leader of the League of Communists of Kosovo in 1982.

Hasani was elected as the Kosovan member of the Yugoslavian presidency in 1984 with his term ending in 1989. He also served as head of the rotating presidency. On Hasani's first day as president, he and his presidency unanimously appointed Branko Mikulić as the federal Prime Minister of Yugoslavia. After Mikulić and his cabinet voluntarily resigned in March 1989, as the first federal ministry in the history of Socialist Yugoslavia, Hasani initially supported the unsuccessful bid of the Milošević loyalist and Serb hardliner Borisav Jović^{[citation needed]}, to become the federal PM. It was contrary to the candidacy of the economically liberal reformist Ante Marković, which was proposed by the republics of Slovenia and Croatia, and finally approved by the Federal Assembly of Yugoslavia, and also by the outgoing presidency, including Hasani himself.

Hasani died in Belgrade on 28 August 2010.

Hasani also wrote a number of novels in Albanian, which were translated into Serbo-Croatian and Macedonian.
