Introduction
Among the many miracles of the Quran, one stands out clearly: its preservation. For more than 14 centuries, the Quran has remained exactly as it was revealed to Prophet Muhammad ﷺ — without additions, deletions, or alterations. This preservation is unique compared to other scriptures, many of which went through revisions and translations.
In this article, we’ll explore how the Quran was preserved, why it remains unchanged, and where readers can access authentic free Tafseer books to study it in depth.
The Divine Promise of Preservation
The Quran itself declares that Allah has guaranteed its protection:
📖 “Indeed, it is We who sent down the Reminder, and indeed, We will be its guardian.” (Quran 15:9)
Unlike previous revelations, the Quran is safeguarded by divine will, ensuring it remains a source of guidance for all humanity until the end of time.
Oral Preservation: The Role of Memorization
From the moment it was revealed, the Quran was recited, memorized, and transmitted orally:
- The Prophet ﷺ recited verses to his companions.
- Many companions memorized the Quran word for word (Huffaz).
- To this day, millions of Muslims across the globe memorize the Quran — from children in villages to scholars in cities.
This oral chain of transmission makes the Quran the most memorized book in history.
Written Preservation: Compilation of the Quran
- During the Prophet’s lifetime, verses were written on parchment, palm leaves, and bones.
- After his passing, Caliph Abu Bakr (RA) ordered a compiled written copy.
- During Caliph Uthman’s (RA) era, the Quran was standardized in a single script, and copies were distributed across Muslim lands.
This Uthmanic Mushaf is the same Quran Muslims read today.
Quranic Text and Its Integrity
Unlike the Bible or Torah, the Quran has remained in Arabic without alteration. Translations exist, but the original Arabic text is preserved universally.
Even modern computer analysis comparing ancient manuscripts (such as those from Sana’a, Yemen) with today’s Quran shows no change in text.

Why the Quran Could Not Be Changed
- Mass memorization made alteration impossible.
- Manuscript standardization prevented textual corruption.
- Daily recitation in prayers ensured preservation in hearts and tongues.
- Divine promise safeguarded it beyond human control.
