Remarkable Structure of the Quran

The Qur’an is a very unique book in terms of its composition. Its 114 chapters (or ‘Surahs’ in Arabic) are not arranged chronologically or thematically. Even within the individual chapters, numerous topics can be covered with sudden switches from one topic to another and then back again.
This unique structure at face value may appear to be disjointed. However, modern research has discovered a sophisticated structural coherence in the Qur’an known as ring composition.
