The Quran, also spelled as Qur’an or Koran, is the holy book of Islam. It is considered the central religious text of Islam and is believed by Muslims to be a revelation from God (Allah) as conveyed to the Prophet Muhammad through the angel Gabriel over a period of approximately 23 years.

The Quran is written in Arabic and is composed of 114 chapters, known as surahs, which vary in length. The chapters are further divided into verses, known as ayahs. The Quran covers a wide range of topics, including theology, morality, guidance for personal conduct, social issues, and legal matters.
