A member of
Džemijet since its foundation in 1919, he was elected mayor of Novi Pazar in 1920. In 1923 he was elected as a representative of the region in the parliament of the
Kingdom of Serbs, Croats and Slovenes. A close collaborator of the party's leader
Ferhat Draga, his speeches in the parliament focused on the agrarian reform, which he often attacked as a policy that targeted only Albanian farmers. During late 1924 and early 1925, Hadžiahmetović was arrested four times under unclear charges and spent the
1925 elections in jail. After Ferhat Draga's imprisonment and the party's dissolution, many of its members faced attacks. Hadžiahmetović himself survived two assassination attempts. In April 1941 German Nazi forces appointed Hadžiahmetović as mayor of Novi Pazar. He established a governing committee in Novi Pazar of 11 members, all Albanians, and also established a Muslim gendarmerie which was pro-Albanian and whose members wore Albanian symbols. His administration violently fired previous local government, many of whom were forced to leave the city. Hadžiahmetović's brother-in-law
Ahmet Daca was appointed as County chief.
Deževa County was given to
occupied Serbia, however Hadžiahmetović and his associates sought a de facto inclusion of Deževa County
occupied Albania through their strong ties with
Tutin. His governance saw a return of feudal relations in the region, which was agreed with
Milan Aćimović, head of
Commissioner Government on July 19. He was one of the signatories of the
Resolution of Sarajevo Muslims in 1941. During that year, his forces began to conduct war crimes against local Serb civilians and started killings of Albanians who were opposed of his rule. he organized the defense of the region against attacks by
Chetnik forces that targeted Albanian and Muslim civilians On October 21, 1941, Hadžiahmetović's troops razed Christian houses in Vojniće and in retaliation, Chetniks razed Muslim houses in the same village. On November 4, Chetnik forces
attacked Novi Pazar for the first time, which was repelled by end of the day. Following their victory in the subsequent battle, the Serbs in the city became victims of violence. Between 4 and 15 November, 67 Christians were killed in the city and near-by villages. Hadžiahmetović's administration did not officially condone killing of Serbs, however it did nothing about it either. Between 5–9 November, Hadžiahmetović's troops burnt down and robbed Christian houses in seven villages and Chetniks followed suit with reprisals to Muslim houses in two villages. On November 16, Hadžiahmetović's troops began a counter-offensive towards
Raška and easily pushed out Chetnik troops, coming in the vicinity of Raška within a day. After the town was captured, tens of Christian villages were robbed and razed by the attacking forces. The Chetniks reorganized and on November 17, managed to push back Hadžiahmetović's forces to Novi Pazar. One of the policies that created the greatest revolt among the local Bosniak population was the prohibition of wearing the Muslim hat,
fez. In 1943 he joined the
Second League of Prizren and was elected a member of its central committee. A few months later, after the incorporation of
Mitrovica into
Albania he became a representative of the region in the Albanian parliament along with Ferhat Abidi, Hysen Hysnija and Shaban Mustafa. Hadžiahmetović organized a conference to promote recruitment for the
SS Handschar in Novi Pazar. One of the speakers at the conference was
Xhafer Deva, head of the administration in
Mitrovica in 1943. In September 1943, Albanian collaborationist forces organized an action against the remaining Serb population in the Draževa srez. 15 Serb villages were burnt down during the action and at least 18 were killed. German police agents noted that Hadžiahmetović was 'hiding the extent of the crimes against Serbs, refusing to persecute the perpetrators and shielding them from justice'. He was considered a collaborator with the Axis powers during World War II and was executed in 1945 by the Yugoslav government, after he was found guilty of the murder of nearly 7,000 Serbs. == Legacy ==
