 At the urging of Zaharije Ostojić, on 25 March 1943, Mihailović appointed Fehim Musakadić as the commander of all Muslim Chetnik units, in the hope that his appointment would encourage Muslims to form Chetnik units.At the end of 1943, Muslims comprised up to eight percent of Mihailović forces, numbering about 4,000.Another prominent Muslim supporter of Mihailović was Mustafa Mulalić, who had been a representative of the Yugoslav National Party in the pre-war Yugoslav parliament.
