Four Main Porposes of Qur'an

The Qur'an aims to guide all people to truth and has four porposes: (1) demonstrating God's existence and Unity; (2) establishing Prophethood; (3) proving and elucidating afterlife, with all its aspects and dimensions; and (4) promulgating the worship of God and the essentials of justice. (Ali Unal, Qur'an Translation, introduction).;
