The Quran is divided into 114 chapters, known as Surahs. Each Surah varies in length and covers different themes, including guidance, morality, and law. The chapters are not arranged chronologically but rather in a specific order that has been preserved since the time of the Prophet Muhammad. Each Surah is further divided into verses called Ayahs. The first Surah, Al-Fatiha, is often recited in daily prayers, while other Surahs address various aspects of life and spirituality. The chapters are central to the practice of Islam and are recited by millions around the world.
