What is the evidence that the Quran is from Allah?

The Quran provides multiple categories of evidence for its divine origin.

1. The linguistic miracle (i'jaz): - Arabic poets of 7th-century Arabia were the most linguistically advanced of their age. - The Quran challenged them to produce even one chapter like it (Quran 2:23, 10:38, 11:13, 17:88). - 14 centuries later the challenge remains unmet despite many attempts. - Its style is neither poetry nor prose, yet exceeds both.

2. The Prophet's character ﷺ: - Known as 'Al-Amin' (The Trustworthy) before prophethood. - Unlettered (could not read or write) yet brought a book of immense knowledge. - Even his enemies could not credibly accuse him of inventing it. Walid ibn Mughirah famously said it 'cannot be the speech of a human' before rejecting it for political reasons.

3. Scientific accuracy: - Embryology stages (Quran 23:12-14) match modern science (Dr. Keith Moore, 'The Developing Human'). - Expanding universe (Quran 51:47). - Mountains as 'pegs' stabilizing the earth (Quran 78:6-7), confirmed by tectonic theory. - Two seas not mixing (Quran 25:53, 55:19-20), observable at the Strait of Gibraltar. - Iron 'sent down' from outer space (Quran 57:25), confirmed by astrophysics.

4. Historical prophecies fulfilled: - Roman victory over Persia within 3-9 years (Quran 30:2-4) — fulfilled. - Conquest of Makkah (Quran 48:27) — fulfilled. - Preservation of Pharaoh's body as a sign (Quran 10:92) — Ramses II's body discovered in 1881.

5. Internal consistency: - Revealed over 23 years across changing circumstances — yet zero contradictions. - Quran 4:82: 'Had it been from other than Allah, they would have found within it much contradiction.'

6. Perfect preservation: - Memorized in full by hundreds of thousands across every generation. - Early manuscripts (Sana'a, Birmingham, Topkapi) match the modern text exactly. - Allah's promise: 'Indeed, We sent down the reminder, and indeed, We will preserve it' (Quran 15:9).

7. Effect on hearts and societies: - Transformed Arabia in 23 years. - Continues to transform individuals across cultures and centuries.

Taken together, the evidence forms an overwhelming case that this book is not of human origin.
