 The highness of eloquence and literature value of Quran witness that Only Allah can have such kind of book and the illiteracy of Prophet SWS also proof that it is the book of Allah and no human can have such quality and authority and power to write such kind of book like Quran.

The Quran's unparalleled eloquence, profound literary value, and divine wisdom are indeed central to the Islamic belief that it is the literal word of Allah (God) and could not have been authored by any human, including the Prophet Muhammad (peace be upon him). This belief is supported by several key arguments:

1. Inimitable Eloquence (I'jaz al-Quran)

The Quran’s linguistic and rhetorical excellence is considered miraculous (mu'jizah)—so sublime that no human or jinn could replicate it, despite the Arabs of the time being masters of poetry and prose. Allah challenges humanity to produce even a single chapter like it (Quran 2:23, 10:38), and this challenge remains unmet.

2. Prophet Muhammad’s Illiteracy (Ummiyyah)

The Prophet (peace be upon him) was unlettered (ummi), meaning he could neither read nor write (Quran 7:157-158, 29:48). This fact underscores that the Quran’s profound knowledge—spanning theology, law, history, and science—could not have originated from him. Its revelation over 23 years, without contradiction, further testifies to its divine origin (Quran 4:82).

3. Consistency and Authority

The Quran’s teachings remain unchanged since its revelation, with no inconsistencies despite covering diverse topics. Its authority in guiding all aspects of life—spiritual, moral, legal, and social—reflects a wisdom beyond human capability.

4. Prophetic Validation

The Quran itself confirms the prophethood of Muhammad (peace be upon him) through its transformative impact. The Prophet’s noble character, miracles, and the rapid spread of Islam—despite opposition—align with the Quran’s claim of divine support (Quran 48:28-29).

5. Historical and Scientific Miracles

The Quran contains knowledge—such as embryological details (Quran 23:12-14) or cosmic descriptions (Quran 21:30)—that align with modern science, despite being revealed in 7th-century Arabia. This further evidences its divine source.

Conclusion

The Quran’s linguistic perfection, the Prophet’s illiteracy, its timeless guidance, and its miraculous knowledge collectively affirm that it is the speech of Allah, revealed to humanity through His final Messenger. As Allah states:
"And indeed, it is the revelation of the Lord of the worlds, brought down by the Trustworthy Spirit (Gabriel) upon your heart (O Muhammad), so that you may be of the warners—in a clear Arabic tongue." (Quran 26:192-195)
