If you have ever picked up a copy of the Holy Quran or heard one being recited at the masjid, you may have wondered where this book actually came from. Who wrote the Quran? Did the Prophet Muhammad ﷺ write it himself? When was it written down, and how has it survived word for word for more than fourteen centuries?
These are fair questions, and they come up often — from new Muslims, from students, and from anyone curious about Islam’s sacred book. Here is a clear answer.
The Short Answer
In Islam, the Quran is the word of Allah. Muslims believe it was not composed by any human being. It is the direct, literal speech of God, revealed to the Prophet Muhammad ﷺ through the Angel Jibreel (Gabriel) over roughly twenty-three years.
The revelations began in 610 CE, when the Prophet ﷺ was forty years old, in the cave of Hira on the outskirts of Makkah. They continued, passage by passage, until shortly before his death in 632 CE in Madinah.
So when people ask who the author of the Quran is, the Islamic answer is firm: no human being composed a single word of it. The Prophet ﷺ received the message, recited it exactly as it came, and conveyed it without addition or alteration.
Who Wrote the Verses Down?
The Prophet Muhammad ﷺ was unlettered — he could neither read nor write. Muslims regard this as one of the signs that the eloquence of the Quran could not have originated with him.
So who physically recorded the verses? A group of trusted companions known as the scribes of revelation. Each time a passage was revealed, the Prophet ﷺ would summon one of them and dictate it. The best known among them were Zayd ibn Thabit, Ubayy ibn Ka’b, Ali ibn Abi Talib and Uthman ibn Affan.
They wrote on whatever was to hand: strips of parchment, dried palm leaves, flat stones, animal bone and pieces of leather all carried fragments of the revelation.
Alongside this, hundreds of companions committed the verses to memory. This dual system — written record and memorisation together — is a central reason the text has remained stable for so long.
In other words: the scribes were the writers. The source was Allah.
When Was the Quran Compiled into One Book?
The verses were not gathered into a single bound volume during the Prophet’s lifetime. They existed across many written records and in the memories of his companions.
After the Prophet’s death in 632 CE, a number of companions who had memorised the entire Quran were killed at the Battle of Yamamah. Umar ibn al-Khattab feared the text could be lost piecemeal, and urged the first Caliph, Abu Bakr, to gather everything into one official copy.
Zayd ibn Thabit was given the task. He cross-checked every verse against multiple memorisers and written sources before including it. The result was the first compiled Mushaf, held by Abu Bakr, then Umar, and later by Umar’s daughter Hafsa.
Around twenty years later, under Caliph Uthman ibn Affan, Islam had spread well beyond Arabia and minor differences in dialect were beginning to appear. To prevent any drift, Uthman ordered standardised copies to be produced from Hafsa’s Mushaf. These were sent to Makkah, Madinah, Kufa, Basra and Damascus around 650 CE.
That standardised text — the Uthmanic Mushaf — is the Quran that Muslims read today.
Why the Quran Differs from Other Scriptures
People often assume the Quran was produced the way some other religious books were: followers writing down what their prophet taught, after the fact.
The Quran is not that. It is not a biography of Muhammad ﷺ, and it is not a record of his sayings. His own words are preserved separately, in the collections of Hadith.
The Quran is presented as direct speech from Allah to humanity, with the Prophet ﷺ as its messenger and reciter. That clear separation between divine revelation and prophetic teaching is one of the most distinctive features of the Islamic tradition, and Muslims are careful never to blur the two.
How the Text Has Survived Word for Word
What is remarkable is not only the question of authorship but the manner of preservation.
Every year, Muslims around the world memorise the Quran in full, becoming Huffaz. If every printed copy were lost tomorrow, the complete text could be reproduced from memory alone.
This unbroken chain of transmission, the Sanad, connects reciters today back to the Prophet ﷺ. No other text of comparable age has been preserved in this way.
For Muslims, this fulfils Allah’s own promise in the Quran that He would guard it from corruption. For anyone encountering Islam’s scripture for the first time, the preservation is often the point at which it starts to make sense.
Frequently Asked Questions
Who is the author of the Quran?
In Islamic belief, Allah. The Quran is understood as God’s own speech rather than a text composed by a human author. The Prophet Muhammad ﷺ was its recipient and reciter, not its writer.
Who wrote the Quran for the Prophet Muhammad ﷺ?
The scribes of revelation recorded the verses as he dictated them. Zayd ibn Thabit, Ubayy ibn Ka’b, Ali ibn Abi Talib and Uthman ibn Affan are the most frequently named. The Prophet ﷺ himself could not read or write.
Who made the Quran into a book?
Zayd ibn Thabit compiled the first single volume on the instruction of Caliph Abu Bakr, shortly after the Prophet’s death. Caliph Uthman later had standardised copies produced from it and distributed to the major centres of the Muslim world around 650 CE.
Is the Koran the same as the Quran?
Yes. “Koran” is simply an older English spelling of the same word. “Quran” is closer to the Arabic pronunciation and is the more common transliteration today.
How long did the revelation of the Quran take?
Approximately twenty-three years — from 610 CE in Makkah until shortly before the Prophet’s death in 632 CE in Madinah. It was revealed gradually rather than all at once, often in response to particular circumstances.
Has the Quran changed over time?
Muslims hold that the text is unchanged, and the evidence usually cited is the dual preservation of written manuscript and mass memorisation, along with the standardisation carried out under Uthman. Early manuscripts such as those held in Birmingham and Sana’a are consistent with the text in use today.
