However, the court deferred the implementation of the verdict, which means Turan will not go to prison unless he commits a crime in the next five years.
Turan was involved in a fight with Turkish singer Berkay Sahin in an Istanbul nightclub late last year, leaving the singer with a broken nose.
Turan later arrived at the hospital with a gun which he fired at the ground, causing panic.
Basaksehir said they had fined the 31-year-old 2.5 million Turkish lira (US$432,548) over the incident.
He joined Barcelona from Atletico Madrid for 34 million euros (US$37.45 million) in 2015, winning four trophies, making 55 appearances and scoring 15 goals for the Catalan club.
Turan has played for Turkey 100 times and scored 17 goals for his country.
