Refuting Islam

Post 7: Islam’s Logical Collapse – Formal Refutation of Its Core Claim

Introduction: The Foundation Is Rotten

Every religion makes truth claims. But Islam does more: it claims to be the only true religion, the final revelation, and the unchanged word of God, sent not just to Arabs but to all of humanity. It says all prior scriptures were Islamic, all previous prophets were Muslims, and the Quran is the final confirmation of all divine truth.

But here’s the problem:

These claims, when tested by formal logic, historical records, manuscript evidence, and internal consistency, self-destruct.

This post will deliver a systematic, airtight, and inescapable logical refutation of Islam’s foundational claims — not based on opinion or theology, but on evidence, contradictions, and deductive reasoning.

By the end, we won’t just show that Islam has errors. We’ll demonstrate that its core structure is logically impossible.

Section 1: The Core Claim of Islam

Let’s define Islam’s central claim clearly:

“Islam is the final, eternal, uncorrupted religion of God, revealed to Muhammad, confirming all previous scriptures, and abrogating them as the final authority.”

This claim is built on the following pillars:

The Quran is the literal, preserved word of Allah.
All prophets before Muhammad were Muslims.
The Torah, Psalms, and Gospel were divinely revealed Islamic scriptures.
The Quran confirms these previous scriptures.
Islam completes and supersedes all prior revelations.

This framework appears internally coherent — until it meets reality.

Section 2: Self-Refuting Contradictions

Let’s apply formal logic to Islam’s claim.

Premises from the Quran:

Surah 3:3 – Allah revealed the Torah and Gospel.
Surah 6:115, 18:27 – “No one can change the words of Allah.”
Surah 5:46 – The Gospel contains guidance and light.
Surah 5:68 – People of the Book should uphold their scriptures.

These premises imply:

The Torah and Gospel were divine, and cannot be corrupted.

But Islam says:

The Bible is corrupted (despite Quranic affirmation).
The crucifixion of Jesus didn’t happen (contradicting all historical and biblical records).
Jesus didn’t claim divinity (contradicted by all Gospel manuscripts).
Abraham built the Kaaba (no historical source says this).

Logical Implication:

If the Quran confirms previous scriptures but those scriptures contradict Islam, then:

Either the Quran is wrong for affirming them, or
Islam is wrong for contradicting them.

You cannot confirm and contradict the same thing. That is a logical contradiction.

Section 3: The Quran’s Fatal Dilemma (David Wood’s “Islamic Dilemma”)

We can now formulate the Islamic Dilemma:

Premises:

The Quran affirms the inspiration, preservation, and authority of the Torah and Gospel (Surah 3:3, 5:47, 6:115).
The Torah and Gospel contradict the Quran on essential doctrines (crucifixion, deity of Christ, salvation, atonement).
Either the Torah and Gospel were preserved, or they were corrupted.

If preserved → Islam is false, because it contradicts preserved truth.
If corrupted → Islam is false, because the Quran affirms texts that no longer exist.

Conclusion: Either way, Islam is false.

Section 4: The Burden of Eternal Preservation

Muslims often boast that the Quran is “unchanged,” “perfectly preserved,” and “unchallengeable.”

But:

The Quran references missing verses (e.g., stoning, suckling).
There were multiple codices (Ibn Mas’ud’s, Ubayy’s) with differing content.
The Uthmanic recension destroyed all other versions.
Early manuscripts (Sana’a, Topkapi) contain variations.

So Islam’s demand for preserved texts boomerangs:

If preservation is required for truth, then the Quran fails.
If earlier scriptures were allowed to be corrupted, then God failed to protect His word — contradicting Surah 6:115.

Islam demands of others what it cannot deliver itself.

Section 5: The Identity Crisis of the Prophets

Islam claims all prophets were Muslims — even when:

They lived before Islam existed
They never heard of Muhammad
They taught doctrines antithetical to Islam

But the definition of a Muslim includes:

Belief in Muhammad as the final prophet
Obedience to the Quran
Performing salat, sawm, zakat, hajj

So Abraham, Moses, and Jesus cannot be Muslims by definition.

To call them Muslims is to:

Change the definition of “Muslim” to mean something else
Commit the fallacy of equivocation
Retroactively impose Islamic categories onto earlier non-Islamic contexts

This renders the Quran’s continuity claim a semantic illusion.

Section 6: Mecca, the Kaaba, and the Historical Void

Islam claims:

Mecca is the “mother of cities” (Surah 6:92)
Abraham and Ishmael built the Kaaba (Surah 2:127)
Hajj was instituted by God for all mankind (Surah 22:27)

Yet:

Mecca is absent from all ancient maps and records.
No external evidence places Abraham anywhere near Arabia.
Early mosques did not point to Mecca (per Dan Gibson’s qibla research).
Archaeological silence surrounding Mecca before Islam is deafening.

This creates another contradiction:

A timeless city of pilgrimage, central to divine worship, yet completely invisible in history.

This is not divine silence. It is post-fabrication.

Section 7: The Quran’s Literary Borrowings and Pagan Residue

Despite claiming to be original and unmatched in eloquence:

The Quran borrows extensively from Jewish Midrash, Christian apocrypha, and Zoroastrianism.
Stories like the “Seven Sleepers of the Cave” and Alexander the Great’s wall against Gog and Magog are lifted with changes.
The Black Stone, circumambulation, and rituals of Hajj trace back to pre-Islamic Arabian paganism.

This results in a religion that:

Plagiarizes Jewish and Christian theology
Reinvents Arab pagan customs as divine revelation
Rejects the very scriptures it mines for content

This is not divine continuity. It is cut-and-paste religion-building.

Section 8: Formal Syllogistic Refutation

Let’s now construct the formal syllogism:

Claim:

Islam is the final, true religion that confirms prior revelations and preserves God's word.

Premises:

The Quran affirms the Torah and Gospel as revealed, authoritative, and preserved (Surah 3:3, 5:46, 6:115).
The Torah and Gospel contradict the Quran’s teachings.
If they are preserved, the Quran contradicts true revelation.
If they are corrupted, the Quran is wrong for affirming them.
The Quran cannot both confirm and deny the same thing (law of non-contradiction).

Conclusion:

Islam is logically incoherent and therefore false.

Section 9: Collapsing from Within – No External Attack Needed

Islam doesn't collapse under external attack. It implodes under its own weight.

Its scriptures:

Affirm what they must reject
Borrow what they later condemn
Contradict what they claim to complete
Depend on revelations they say were lost
Retain rituals they say were purified

It is a house of cards. Once you pull one claim, the rest fall.

Conclusion: A Final Verdict

The previous six posts exposed the historical, textual, theological, and archaeological flaws in Islam’s narrative.

This final post draws the only possible conclusion:

Islam is not just flawed — it is self-defeating.

Its own texts, logic, and structure contradict one another so deeply that no amount of apologetics can reconcile them.

A system that violates the law of non-contradiction cannot be true. A religion that affirms and denies the same thing is not from God.

Islam is false — by its own standard.

Disclaimer

This post critiques Islam as an ideology, doctrine, and historical system—not Muslims as individuals. Every human deserves respect; beliefs do not.
