France remains in a state of emergency after Islamist gunmen and suicide bombers killed 130 people in a series of jihadist attacks in and near Paris in November last year.
A police source said the 28-year-old man of European origin arrested at Disneyland had been carrying the guns, one of them an automatic handgun, concealed in a bag with the religious text.
The Interior Ministry said police were also searching for a woman who may have been with the man, correcting a previous statement that she had been arrested.
"Firearms were discovered in the bags of a man as he went through the metal detector during a routine security check at one of our hotels," Disneyland Paris spokesman Francois Banon said.
Euro Disney (EDLP.PA), whose main shareholder is U.S.-based Walt Disney Co (DIS.N), runs the amusement park.
The man was unknown to police before the incident at the park's New York Hotel, the source said.
