The Quran is thought by Muslims to be not simply divinely inspired, but the literal word of God.

Muhammad did not write it as he did not know how to write. According to tradition, several of Muhammad's companions served as scribes, recording the revelations. Shortly after the prophet's death, the Quran was compiled by the companions, who had written down or memorized parts of it.

Caliph Uthman established a standard version, now known as the Uthmanic codex, which is generally considered the archetype of the Quran known today. There are, however, variant readings, with mostly minor differences in meaning.

Muslims believe the Quran to be God's final revelation to humanity, a work of divine guidance revealed to Muhammad through the angel Gabriel.

Respect for the written text of the Quran is an important element of religious faith by many Muslims, and the Quran is treated with reverence. Based on tradition and a literal interpretation of Quran 56:79 ("none shall touch but those who are clean"), some Muslims believe that they must perform a ritual cleansing with water (Wudu or Ghusl) before touching a copy of the Quran, although this view is not universal.

The Quranic content is concerned with basic Islamic beliefs including the existence of God and the resurrection. Narratives of the early prophets, ethical and legal subjects, historical events of Muhammad's time, charity and prayer also appear in the Quran. The Quranic verses contain general exhortations regarding right and wrong and historical events are related to outline general moral lessons. Verses pertaining to natural phenomena have been interpreted by Muslims as an indication of the authenticity of the Quranic message.
