The Quran, Islam's holy book, was not revealed all at once. Rather, it came to Prophet Muhammad (peace be upon him) in stages over about 23 years. The order of revelation provides deep insights into the formation of the early Muslim community and the gradual evolution of Islamic law and principles.
Scholars have critically examined each chapter and verse of the Holy Book, attributing them generally into Meccan and Medinan periods. Meccan revelations, occurring prior to the migration of the Prophet to Medina, were almost exclusive in fixing the fundamental Islamic teachings: Oneness of God (Tawhid), Messianism of prophets, judgment after death (Qiyamat al-Qabr), and virtues/ethics of life. All these earlier verses tended to make use of energetic imagery as they spoke regarding idolatric sentiments that characterized the city of Mecca.
Subsequent to migration at Medina, revelations turned socio-political in legislation, enacting laws governing worship, family life, state affairs, and war. Medinan surahs dealt with the day-to-day needs of the new Muslim state and preached norms for developing an equitable and equitable society.
Reading the revelation order of the Quran gives one a chronological understanding of how Islamic thought and practice evolved. It emphasizes the purpose behind the sequential revelation of the intricate laws and the focus on core beliefs before dealing with structures in society. This gradual revealing points to the divine pedagogy in educating faith and guiding humankind toward truth.
