According to Muslim teachings, God first revealed His word in the Holy Qur'an to the prophet, Muhammad, during the month of Ramadan. That word has guided billions of believers across the centuries, and those believers built a culture of learning and literature and science. All the world continues to benefit from this faith and its achievements.
Human beings are of such nature that they should have not only material facilities but spiritual sustenance as well. Without spiritual sustenance, it is difficult to get and maintain peace of mind.
