Is the Qur’an really the word of Allah?
Chapter 03
Why the Qur’an is the word of Allah
How do we know today’s Qur’an is the one the Prophet ﷺ recited?
Before a single verse of the Qur’an came down, a man in Makkah named Zayd ibn Amr was already looking for it. He’d rejected the idols around the Kaabah, challenged his own family for slaughtering to things that created nothing, and travelled as far as Syria asking Jewish and Christian scholars for the religion of Ibrahim. None of them could give him what he was looking for. He was later seen leaning against the Kaabah with his hands raised, asking Allah to show him the worship He loved, because he knew there was a Lord, and still didn’t know how to reach Him.
That’s the hunger the Qur’an answered. It doesn’t present itself as Muhammad’s reflections about God. It speaks as Allah addressing His creation, and it records a promise within it: “We have revealed the Reminder, and We will preserve it.” Preservation can’t prove by itself that Allah spoke. It does however mean the text making the claim is still here to be examined rather than reconstructed from copies that disagree about what the original said.
The Birmingham manuscript carries parts of Surahs al-Kahf, Maryam, and Taha on parchment, dated right to the time of the Prophet and his companions. But manuscripts alone aren’t how the Qur’an survived; it was memorised as it came down, written during his lifetime, collected by the first generation, and recited out loud in every prayer. Today, two billion Muslims carry that text through millions of mosques, homes, and schools. If you put one of those early fragments beside a modern print, and then listen to the same passage recited thousands of miles away, you find they are the exact same words. Its recognised readings still pass through named teachers, including the Warsh recitation I grew up hearing in Morocco. Memory checked the page, the page checked memory, and public recitation kept the text from belonging to a private room where somebody could quietly change it.
Then open it. The revelation came over twenty-three years. During that time, the man carrying it was mocked, lost his children, was driven from his home, and eventually returned to Makkah in power. Yet through all of it, the voice remains distinctly above him. It consoles him, corrects him, refuses to flatter his family, and never turns victory into self-worship.
You also meet the same call inside it that ran through Ibrahim, Musa, and Isa: worship the Creator alone, answer for the life you were given, and don't hand Allah’s rights to what He made. The preservation, the Messenger’s life, the coherence, and the voice of the Book - they belong to a single, undeniable reality. Even people who know no Arabic feel addressed when they hear it. That pull isn't just an emotion to be argued away; it is a reason to finally stop reading arguments about the Qur’an, and simply read the Qur’an.
This is the short answer. Chapter 3 of the book takes it all the way.
