The Quran is the central religious text of Islam, which Muslims believe to be a revelation from God (Arabic: الله‎, Allah). It is widely regarded as the finest piece of literature in the Arabic language. The Quran was revealed in the form of a book, and since then has been preserved in a fixed, written form in the Arabic language. It is composed of 114 chapters, which are arranged in a specific order. In some verses, the order is chronological, while in others it is the reverse chronological. This allows the reader to read from the beginning of a chapter to the end of the last chapter. Each chapter is divided into sections called suras. Every sura is composed of verses. The Quran is divided into different chapters to avoid repetition and to facilitate the reading of the whole text by the reader. Every chapter is composed of a verse or verses. Every verse is composed of one or more letters. The letters of the Quran are arranged in a specific order, which is known as the Haditha. The word 'Haditha' is derived from the Arabic word 'ادع‎', which means "oral literature". This form of literature is composed of the hadiths, the stories and the accounts that are passed on from one generation to another. Each chapter of the Quran is composed of one or more of the letters of the alphabet.
