If the Gospel Was Corrupted… Then What Was It?
Why the Qur’an’s Silence on the Injil’s Content Dismantles Islam’s Claims
One of Islam’s most central but least examined contradictions lies in its relationship to the Injil—the Gospel revealed to Jesus.
Muslims commonly claim that the Injil was a real, divine book given by Allah to Jesus, but that it was later corrupted by Christians. This belief underpins their rejection of the New Testament and their insistence that the Qur’an came to "correct" the record.
But this raises a fatal dilemma:
❗ If the Injil was corrupted...
Why doesn’t the Qur’an ever define or describe what its actual, uncorrupted content was?
Despite repeatedly referencing the Injil, the Qur’an never quotes it, summarizes its message, or defines its theological core.
Let’s unpack why this is a devastating problem for Islamic theology.
📜 1. The Qur’an Commands Christians to Judge by the Injil
This alone is enough to expose the contradiction.
“Let the People of the Gospel judge by what Allah has revealed therein.” — Surah 5:47
This is not a reference to a lost or corrupted text—it clearly refers to a present, accessible Gospel that Christians are told to use as authoritative in Muhammad’s time.
If the Gospel was corrupted, then:
-
Why would Allah command Christians to judge by it?
-
Why does the Qur’an affirm what they have?
Either the Gospel existed in its true form… or Allah gave a contradictory command.
Either way, Islamic theology collapses.
🤐 2. The Qur’an Never Tells Us What the “True” Gospel Contained
If the Injil was corrupted—what was corrupted?
Why doesn’t the Qur’an include:
-
A summary of the Injil’s core message?
-
A restatement of Jesus’ actual teachings?
-
A correction of specific falsehoods introduced by Christians?
It does none of this.
Instead, the Qur’an:
-
Speaks vaguely of Jesus being given a “book” (Q 5:46)
-
Mentions the Injil over a dozen times
-
But never provides its content
That’s like accusing a journalist of altering a report, but refusing to reveal what the original report actually said.
This isn’t divine precision. It’s deliberate theological vagueness, likely to protect Muhammad from exposing his ignorance of Christian scripture.
⚖️ 3. The Qur’an Repeatedly Affirms the Scriptures of the People of the Book
Surah 3:3 says:
“He has sent down upon you the Book in truth, confirming what was before it. And He revealed the Torah and the Gospel.”
But “confirming” a corrupted book is illogical.
And if the Torah and Injil were corrupted, the Qur’an should have rebuked them clearly—yet it never does.
Even worse, Muhammad is told to say:
“If you are in doubt about what We have revealed to you, ask those who read the Book before you.” — Q 10:94
What “Book” are they reading?
Obviously, the Torah and Gospel known in the 7th century—which we still have today.
Again: the Qur’an points to these texts as reliable witnesses.
🧩 4. Post-Qur’anic Muslims Invented the “Corruption” Narrative
Early Muslims did not accuse the Torah or Gospel of being corrupted textually. This idea only appears centuries later, as a desperate response to Christian and Jewish critiques.
Early Islamic scholars (like al-Tabari) argued that the Jews and Christians had misinterpreted their texts—not that the texts themselves were forged.
But as Christian apologists began quoting chapter and verse, showing contradictions between the Bible and Qur’an, Muslim scholars were forced to evolve their defense:
“The Bible has been altered!”
But this is nowhere in the Qur’an.
🧨 5. Islam Cannot Define What It Rejects
This is the core weakness:
-
The Qur’an tells Christians to follow the Gospel.
-
It affirms its divine origin.
-
It never identifies what the original Gospel taught.
-
It never defines the “corruption.”
-
And it offers no alternate text in its place.
This is not divine clarity—it’s doctrinal incoherence.
The moment a Muslim says, “the Injil was corrupted,” ask:
❓ “What exactly was corrupted? What did the original Injil say?”
If they can’t answer that—if the Qur’an doesn’t answer that—then how can they reject the New Testament with any authority?
🔚 Conclusion: A Theological Trap Without an Exit
The Qur’an wants to claim:
-
That the Gospel is divine.
-
That it’s been corrupted.
-
That the Qur’an confirms it.
-
That Christians should still use it.
-
That it has no contradictions with Islam.
These claims are mutually exclusive.
It’s a theological house of cards—built on ambiguity, collapsing under scrutiny.
The Qur’an’s failure to define the Gospel it praises is not just a minor oversight.
It is the fatal flaw that unravels Islam’s claim to continuity with Biblical revelation.
And in the end, it proves the opposite of what it claims:
That Muhammad did not know what the true Gospel was—and that the Qur’an’s references to it are echoes of ignorance, not affirmations of truth.
