 According to author Ziauddin Sardar, the movement has created a "global craze in Muslim societies".The "ijaz" movement/industry is "widespread and well-funded" with "millions" from Saudi Arabia.Enthusiasts of the movement argue that the Quran abounds with "scientific facts" centuries before their discovery by science and thus demonstrating that the Quran must be of divine origin, "with no single verse (Ayah) in the Qur’an that is proved incorrect by the science".
