Why is the Qur’an important to Muslims?

The Quran is the last holy book that Allah sent to people. The Koran was transmitted to the Prophet Muhammad through Gabriel (Jibril), and then it has come down to our days.
The Qur’an is a material and spiritual guide for people and communities, all classes of people, living in any place or time and for the entire life of a person. Everyone, from the president to the average person on the street, finds useful things that are described in the Quran. They take the knowledge and lessons necessary for peace and tranquility both in the world and in the future.
