Praise be to Allaah who brought down the Qur'aan with the simplest faces and the clearest languages, and we are worshiped by his liberation and perfecting his reading, and making it one of the greatest sacrifices, and prayers and peace be upon his prophet Muhammad . The Quranic readings have not yet been published, and in response, studies have been published in order to make it easier for them, especially linguistics, towards their different grammatical, vocal and semantic tendencies, and how their origin is not derived from the Qur'an.
