Jonathan Kodjia scored the match-winning goal as Al Gharafa pipped Al Arabi 1-0 in their first Qatar Stars League game since March.
The Ivory Coast international's goal separated the two teams at the Al Janoub Stadium on Friday after completing a fine team move with his calm finish in the 22nd minute.
The strike was Kodjia's fifth goal in the Stars League after making six appearances since his January signing from Premier League club Aston Villa.
He was in action for the duration as Al Gharafa boosted their chances of qualifying for the AFC Champions League next season.
