Early on in the Arabic literary world, there has been a culture of academic criticism. The poetry festivals of the pre-Islamic period often pitched two poets against each other in a war of verse in which one would be deemed winner by the audience. Literary criticism also grew into theology, and thus gained a more official status with Islamic study of the Qur'an. Although nothing which might be termed 'literary criticism', in the modern sense, was applied to a work held to be "i'jaz" or inimitable and divinely inspired, an analysis was permitted. This study allowed for a better understanding of the message and facilitated interpretation for practical use, all of which help the development of a critical method important for later work on other literature. A clear distinction regularly drawn between works in literary language and popular works has meant that only part of the literature in Arabic was usually considered worthy of study and criticism.
