The Noble Qur'an is the central religious text of Islam. Muslims believe the Qur’an is the book of Divine guidance and direction for mankind, and consider the original Arabic text the final revelation of Allah (God).
The Meccan suras are the chronologically earlier chapters (suras) of the Qur'an that were, according to Islamic tradition, revealed anytime before the migration of the Islamic prophet Muhammed and his followers from Mecca to Medina (Hijra). The Medinan suras are those revelations that occurred after the move to the city of that name.
The Medinan suras or Medinan chapters of the Qur'an are the latest 24 suras that, according to Islamic tradition, were revealed at Medina after Muhammad's hijra from Mecca. These suras were revealed by Allah when the Muslim community was larger and more developed, as opposed to their minority position in Mecca.
