Al-Quran is the primary source of religious knowledge for Muslims. It contains the basic information about God, His creation, the miracles He performed, and the laws He instituted. A believer is expected to know and understand its contents and to believe in its authenticity. 

The Quran is divided into chapters, which are then divided into verses. Each verse is composed of two or three letters, called al-faqir. The meaning of the verses is often difficult to understand, but the meaning of the whole chapter is clear and straightforward. 

In the Quran, God tells His followers that He created the universe and mankind in a specific way, and that the universe and mankind are destined to undergo various trials and sufferings. 

The Quran contains a number of teachings and beliefs, some of which are accepted by all Muslims and others of which are considered by some to be extreme or difficult to understand. These teachings and beliefs include the following:

The existence of God and His power and ability to create the universe and mankind. 

The creation of the universe and mankind by God in a specific way, and the consequences of this creation. 

The truthfulness of God, and the authenticity of the Quran. 

The significance of the Quran in Islam and the mission of its reciters. 

The different forms of God and the nature of God’s relationship with mankind.
