Musa reportedly informed Sivasspor of his decision to quit the club last December.
Both parties have now agreed to terminate his contract.
Sivasspor are owing the player six months salary.
The versatile forward is already working on a move to another club in the summer.
Musa joined Sivasspor from another Turkish outfit, Fatih Karagumruk in 2022.
He made 19 league appearances for the club without a goal to his name.
