Historicity of the Quran

The Quran is viewed to be the scriptural foundation of Islam and is believed by Muslims to have been sent down by Allah (God) and revealed to Muhammad by the angel Jibreel (Gabriel). Muslims have not used historical criticism in the study of the Quran, but they have used textual criticism in a similar way used by Christians and Jews. It has been practiced primarily by secular, Western scholars such as John Wansbrough, Joseph Schacht, Patricia Crone, and Michael Cook, who set aside doctrines of the Quran's divinity, perfection, unchangeability, etc., accepted by Muslim scholars, and instead investigate the Quran's origin, text, composition, and history.

Scholars have identified several pre-existing sources for some Quranic narratives. The Quran assumes its readers' familiarity with the Christian Bible and there are many parallels between the Bible and the Quran. Aside from narratives from the Christian Bible, the Quran includes legendary narratives about Dhu al-Qarnayn, apocryphal gospels, and Jewish legends.

Some philosophers and scholars such as Mohammed Arkoun, who emphasize the mythological content of the Quran, are met with rejectionist attitudes in Islamic circles. In the Muslim world, scholarly criticism of the Quran can be considered an apostasy. Scholarly criticism of the Quran is thus a nascent field of study in the Islamic world. Another relatively new interpretation of historical figures in the Qur'an is that the characters mentioned are not historical figures but certain typologies of evil people such as Nimrod (the king who humiliated and imprisoned Abraham), Haman, Qarun and Pharaoh, which Muslims should understand as concepts related to human beings.
