The producers of a Japanese TV anime series apologized Saturday for using what sounds like the Muslim call to prayer in the program's background music.

A source related to the producers of "Noragami Aragoto," a polytheistic battle fantasy literally meaning "Stray God, Rough Style," said a person claiming to be Muslim complained that the call to prayer was mixed in with the show's music, which aired on television.

The recording in question was purchased from a licensed source, according to the producers of the series.

"There was never any intention to insult Muslims or blaspheme Islam," the producers said in a statement posted on the program's official website. "The sound was recorded and published without examining its meaning, which resulted in the (inadvertent) lack of consideration to Islam and its followers."

"We deeply apologize that the use of the sound in the work has potentially caused offense to Muslims and related people," the statement said.

The producers pledged to prevent the reoccurrence of a similar mistake by deepening their understanding of Islam and ensuring they pay more attention to the content of future programs.

Further shipments of the program's soundtrack, which went on sale Nov. 25, will be canceled and the existing compact disc inventory will be removed from stores.

The sale of DVDs and Blu-ray discs will be postponed from the originally scheduled Dec. 18 date to allow for the offending music to be replaced.
