In Islam, ’i‘jāz (Arabic: اَلْإِعْجَازُ, romanized: al-’i‘jāz) or inimitability of the Qur’ān is the doctrine which holds that the Qur’ān has a miraculous quality, both in content and in form, that no human speech can match. According to this doctrine the Qur'an is a miracle and its inimitability is the proof granted to the Prophet Muhammad in authentication of his prophetic status. It serves the dual purpose of proving the authenticity of its divineness as being a source from the creator as well as proving the genuineness of Muhammad's prophethood to whom it was revealed as he was the one bringing the message.
