Ziyech's dispute with Halilhodzic was a factor in the Moroccan soccer federation's decision to fire the Bosnian coach last month despite leading the team through qualifying for the World Cup.
Halilhodzic left out Ziyech last year, and for the African Cup of Nations in January, over a supposed unwillingness to play in a friendly game.
New coach Walid Regragui included Ziyech in his first squad of 31 players for games in Spain against Chile and Paraguay, which did not qualify for the World Cup. Both games are being played in Spain on Sept. 23 and 27, respectively.
Morocco is in a World Cup group with Croatia, Belgium and Canada. The tournament is played in Qatar from Nov. 20-Dec. 18.
