Has the Bible been preserved or corrupted — what does Islam teach about this?
Short Answer
Islam teaches that the original revelations to Moses ﷺ (the Torah) and Jesus ﷺ (the Gospel/Injeel) were divine. However, the Quran also teaches that over time, these scriptures underwent tahrif — deliberate alteration and textual corruption. This is confirmed by mainstream biblical scholarship, which documents thousands of manuscript variants, editorial additions, and inconsistencies across biblical manuscripts. The Bible we have today is not the original preserved revelation — it is a compiled collection of texts that has been copied, translated, and edited across centuries.
Detailed Explanation
This is one of the foundational differences between the Islamic and Christian views of scripture — and it helps explain why Muslims and Christians often speak past each other on biblical authority.
The Islamic Position Clarified
Islam does NOT say:
- The original Torah was false
- The original Gospel (Injeel) given to Jesus ﷺ was false
- God failed to send guidance through Moses and Jesus
Islam DOES say:
- Those original revelations were genuine and divine
- The texts that survive today do not accurately preserve those original revelations
- Human scribes, translators, and editors introduced alterations (tahrif) over centuries
- This is why Allah sent the Quran as a final, preserved revelation
The Quranic Support
Multiple Quranic verses address this directly:
"Among those who are Jews, there are some who alter words from their [proper] places." (An-Nisa 4:46)
"So woe to those who write the scripture with their own hands, then say, 'This is from Allah,' in order to exchange it for a small price." (Al-Baqarah 2:79)
“And indeed, there is among them a party who alter the Scripture with their tongues so you may think it is from the Scripture, but it is not from the Scripture. And they say, 'This is from Allah,' but it is not from Allah.”

This is not simply a Muslim claim — it is the consensus of secular biblical scholarship:
- Thousands of manuscript variants — biblical scholars estimate over 400,000 textual variants among surviving New Testament manuscripts. Bart Ehrman, a leading New Testament scholar (and former evangelical Christian), writes: "We have only error-ridden copies of the originals."
- No original manuscripts — We have zero original autograph manuscripts of any biblical book. Every manuscript is a copy of a copy of a copy. The earliest complete New Testament manuscripts date to the 4th century CE — over 300 years after Jesus ﷺ.
- Known forgeries — Scholars identify pseudepigraphical texts (books falsely attributed to apostles) in the New Testament. Most scholars today believe, for example, that the Pastoral Epistles (1–2 Timothy, Titus) were not written by Paul.
- Later interpolations — The story of the woman caught in adultery (John 7:53–8:11) does not appear in the oldest manuscripts. The ending of Mark (16:9–20) also does not appear in the oldest manuscripts. These are acknowledged additions to the biblical text, not original scripture.
- The Council of Nicaea (325 CE) — The canonisation of the Christian Bible was ultimately a human decision. Hundreds of texts competed for inclusion. Texts like the Gospel of Thomas, Gospel of Peter, Shepherd of Hermas, and dozens of others were excluded by Church councils.
The Oral Transmission Problem
Jesus ﷺ spoke Aramaic. His words were passed orally in Aramaic for decades. The Gospels were written in Greek — a different language — by authors who were not eyewitnesses to Jesus's ministry. Then these Greek manuscripts were copied repeatedly, translated into Latin (Jerome's Vulgate, 4th century), and much later into English (King James Version, 1611 — over 1,500 years after Jesus). Each step in this chain introduced the potential for alteration.
The Contrast with the Quran's Preservation
The Quran was revealed in Arabic and memorised in Arabic by thousands of companions during Muhammad ﷺ's lifetime. The Prophet ﷺ personally approved the memorisation and recitation of every verse with the sahaba. Within 20 years of his death, a standardised written Quranic text (Mushaf Uthman) was compiled and distributed. Today's Quran is letter-for-letter identical to the earliest surviving manuscripts (Sana'a manuscripts, Birmingham Quran manuscript dated 568–645 CE). There are no manuscripts of the Quran that contain textual variants of substance.
Allah's promise: "Indeed, it is We who sent down the Reminder [Quran] and indeed, We will be its guardian." (Al-Hijr 15:9)
“Indeed, it is We who sent down the Reminder [the Quran] and indeed, We will be its guardian.”
