I'jaz

In Islam, ’i‘jāz (Arabic: اَلْإِعْجَازُ, romanized: al-ʾiʿjāz) or inimitability^{[citation needed]} 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.^[1] According to this doctrine the Qur'an is a miracle and its inimitability is the proof granted to 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, an unlettered man who could not read nor write, to whom it was revealed.
