In Islam, ’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 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; and proving the genuineness of Muhammad's prophethood to whom it was revealed as he was one bringing the message.

(2:23) In the verses cited, Muhammad's opponents are invited to try to produce a text like the Qur'an, or even ten chapters, or even a single chapter. It is thought among Muslims that the challenge has not been met. Study The literary quality of the Qur'an has been praised by Muslim scholars and by many non-Muslim scholars. Some Muslim scholars claim that early Muslims accepted Islam on the basis of evaluating the Qur'an as a text that surpasses all human production. Whilst western views typically ascribe social, ideological, propagandistic, or military reasons for the success of early Islam, Muslim sources view the literary quality of the Qur'an as a decisive factor for the adoption of the Islamic creed and its ideology, resulting in its spread and
