📘 The Fatal Self-Contradiction: Why Muslims Can't Use the Bible to Defend Muhammad

---

🔥 Introduction

Muslim apologists often appeal to the Bible to defend Muhammad’s prophethood.
They argue:

“The Bible shows that prophets don't need miracles — so Muhammad could still be a prophet even if he didn’t perform miracles.”

Or they argue:

“Muhammad is foretold in the Bible — so Christians should accept him.”

But this tactic backfires completely.
It creates a fatal logical contradiction that Muslims cannot escape.
In this post, we will show why Muslims cannot consistently use the Bible to defend Muhammad without destroying their own theology and exposing Muhammad as a false prophet.

📚 Step 1: Islam Declares the Bible Is Corrupted

✅ The Qur'an and Islamic tradition accuse the Jews and Christians of corrupting their scriptures:

• Surah 2:79:

  "Woe to those who write the book with their own hands and then say, 'This is from Allah.'"

• Surah 3:78:

  "Among them are people who twist the Scripture with their tongues."

• Surah 5:13:

  "They changed the words from their places and have forgotten a portion of that which they were reminded of."

✅ Muslim scholars universally argue:

• The Torah and Gospel as they exist today are not the originals.

• They have been textually corrupted and cannot be trusted fully.

🧠 Step 2: Logical Consequence:

➡ If the Bible is corrupted, then Muslims cannot use it to prove anything.

📌 Simple forensic rule:

• If you declare a document forged or unreliable,

• ➡ You cannot then selectively quote it as credible evidence for your claims.

✅ You cannot both say:

• "The Bible is corrupted!"
  and at the same time:

• "The Bible proves Muhammad is a prophet!"

🔴 This is textbook special pleading — a logical fallacy.

📚 Step 3: If the Bible Were Reliable Enough to Use...

Let’s assume for a moment — just for argument’s sake — that Muslims were right to use the Bible.
Then the Bible’s standards must be applied consistently.

The Bible says:

• Deuteronomy 18:20–22:

  "If a prophet presumes to speak in my name something I have not commanded, or speaks in the name of other gods, that prophet must die... If what a prophet proclaims in the name of the Lord does not take place or come true, that is a message the Lord has not spoken."

• Jeremiah 23:16:

  "They speak visions from their own minds, not from the mouth of the LORD."

• Galatians 1:8:

  "But even if we or an angel from heaven should preach a gospel other than the one we preached to you, let him be under God’s curse!"

✅ Applying Biblical standards:

Test	Muhammad’s Record
Consistent unchanging revelation?	❌ No (abrogations admitted: Qur'an 2:106, 16:101)
No contradictory teaching?	❌ No (e.g., free will vs. fatalism contradictions)
Faithfulness to Biblical Gospel?	❌ No (denies crucifixion, divinity, resurrection of Christ)
No false prophecies?	❌ No (e.g., promise that Muslims would conquer Byzantines quickly – Surah 30:2-4, took far longer)

➡ Therefore, by the very Bible Muslims appeal to, Muhammad fails the test of a true prophet.

📚 Step 4: The Qur'an Commands Christians and Jews to Judge by Their Scriptures

The Qur'an itself tells Christians and Jews to judge by what they have:

• Surah 5:43:

  "But how do they make you their judge while they have the Torah in which is Allah's judgment?"

• Surah 5:47:

  "Let the People of the Gospel judge by what Allah has revealed therein."

• Surah 5:68:

  "Say, 'O People of the Book, you have no ground to stand upon unless you uphold the Torah, the Gospel, and what has been revealed to you from your Lord.'"

✅ The Qur'an acknowledges that Christians and Jews had the Torah and Gospel during Muhammad’s time.
It commands them to judge based on it.

---

🔥 Step 5: Applying the Bible's Standards — Muhammad Fails

📌 Christians and Jews, judging by the Bible, would conclude:

• Muhammad contradicts the essential doctrines of the Torah and the Gospel.

• Muhammad brings revelations that alter God's eternal Word (e.g., rejecting the crucifixion).

• Muhammad permits things God had forbidden (e.g., polygamy beyond the Torah’s limits, waging offensive wars).

✅ Thus, Muhammad would be judged a false prophet — not a true one — by Biblical standards.

Muslims cannot accept the Bible to support Muhammad without simultaneously condemning him.

🎯 Final Logical Summary

Step	Result
Islam claims the Bible is corrupted.	❌
Muslims quote the Bible to defend Muhammad.	🔴 Contradicts their own claim
If the Bible is reliable, Muhammad fails its tests.	✅ Muhammad judged false prophet
If the Bible is unreliable, quoting it is meaningless.	✅ Argument collapses

---

📢 Final Verdict:

Muslim apologists cannot use the Bible to defend Muhammad without fatally contradicting their own theology.
If the Bible is reliable, Muhammad fails.
If the Bible is corrupted, it cannot be used as evidence.
Either way, the Islamic case for Muhammad collapses.
