Harun started his senior career in 1988, when he started playing in the Second Yugoslav League club Liria Prizren where he won a place in the first team and started having some great exhibitions, crowned with nine goals. This earned him a trip to the Yugoslav capital Belgrade where, in January 1990, he started to play for the Yugoslav First League club Rad Beograd. Having failed to impress there due to the heavy competition in the squad, in January 1991, he moved to the ambitious Second League club FK Priština, the most successful Kosovar club and nowadays called by its Albanian language form KF Prishtina. After the breakup of SFR Yugoslavia, Aron went to Germany where he first played for Hertha Zehlendorf, and in 1994 signed for the famous Bundesliga club Hertha BSC. After one season, he left for another Berlin club Tennis Borussia Berlin where he consolidated a place in the team and stayed with the club four seasons. In 1999 he signed for Erzgebirge Aue but, after one season, returned to the German capital, this time to play for 1. FC Union Berlin. In summer of 2002 aged 33 years, Harun moved to VfL Osnabrück where he played two seasons before retiring in 2004.
