According to the unanimous consensus of Islamic scholarship, the Quran (القرآن, al-Qur'an) is the literal, uncreated word of God (Allah), revealed in Arabic to the final prophet, Muhammad, over 23 years. As the central and sacred text of Islam, it is not merely a book but a divine recitation ('the recitation'), a direct communication from the Creator that serves as the ultimate source of guidance, law, and spiritual healing for all humanity. Classical authorities like Imam al-Tabari emphasize its linguistic inimitability (I'jaz) as a proof of its divine origin, a miracle in itself. Across its 114 chapters (surahs), a cross-verse synthesis reveals its primary themes: the absolute oneness of God (Tawhid), the lineage of prophets, the certainty of the Day of Judgment, and a complete code for a just and ethical life. The Quran describes itself as 'The Book' (al-Kitab), 'The Criterion' (al-Furqan), and 'The Reminder' (al-Dhikr), and Allah Himself guarantees its preservation (Quran 15:9), a promise fulfilled through meticulous compilation by the Prophet's companions and mass memorization by Muslims throughout history. This ensures its status as the unaltered, final revelation for all time.
