The Doctrine of ʿIsmah: Divine Infallibility or Theological Fiction?

---

🧩 Introduction: What Is ʿIsmah?

ʿIsmah (Arabic: عِصْمَة) is the Islamic doctrine of infallibility — the belief that certain individuals are divinely protected from sin, error, forgetfulness, and especially from delivering incorrect revelation.

In Islam, this doctrine is applied differently by sects:

• Sunni Islam: Applies ʿIsmah only to prophets, and only in matters of delivering revelation.

• Shia Islam (Twelver): Extends ʿIsmah to prophets, Fatimah (Muhammad’s daughter), and the Twelve Imams in all aspects of life.

But is this doctrine defensible — scripturally, logically, or historically?

1️⃣ The Theological Motivation: Why ʿIsmah Was Invented

The concept of ʿIsmah wasn’t revealed — it was constructed post hoc to protect theological infrastructure.

❓Why was it needed?

• To shield prophetic authority from criticism.

• To defend the authenticity of the Qur’an.

• To justify Sharia as perfectly conveyed and interpreted.

• In Shia Islam: to defend Imamate as the only source of unerring guidance.

🧠 Without ʿIsmah, any mistake by a prophet or Imam casts doubt on the entire religion’s credibility. The doctrine thus functions as a safety net for divine authority, not a self-evident truth.

2️⃣ Qur’anic and Historical Refutation: Infallibility Denied by the Qur’an Itself

🔥 A. Prophets Commit Errors and Sins

Even the Qur’an portrays prophets as fallible human beings:

Prophet	Error/Sin	Reference
Adam	Disobeyed God’s command	2:36, 7:22–23
Moses	Killed a man, then repented	28:15–16
Jonah	Fled his mission	37:139–142
David	Judged unfairly	38:24–25
Muhammad	Turned away from the blind man	80:1–10
Muhammad	Rebuked for premature actions in battle	8:67–68
Muhammad	Forgot verses of the Qur’an	Bukhari 5038–5039

This isn’t minor. These are moral or judgmental lapses — a direct contradiction of the claim that prophets are immune from sin or error.

🔥 B. The Satanic Verses: ʿIsmah’s Fatal Blow

The most serious challenge to ʿIsmah is the Satanic Verses incident, recorded in early Islamic histories:

📚 Sources:

• Al-Ṭabarī, Tārīkh al-Rusul wa al-Mulūk

• Ibn Ishaq via Ibn Hishām

• Ibn Saʿd, al-Ṭabaqāt

• Al-Wāqidī

Muhammad allegedly recited verses accepting pagan goddesses (al-Lāt, al-ʿUzzā, and Manāt) as valid intercessors. The Quraysh rejoiced. Later, he retracted those verses and said Satan made him say them.

Alleged words:

“These are the exalted gharānīq (cranes), whose intercession is hoped for.”

These verses were removed from the Qur’an. But the incident left a stain that theological gymnastics cannot erase.

Qur’anic admission?

Qur’an 22:52 – “Never did We send a messenger or a prophet before you but that Satan cast into his desire. But Allah abolishes what Satan casts...”

This is a blatant contradiction of infallibility in revelation.

3️⃣ Sectarian Inflation: Sunni vs. Shia Breakdown

Aspect	Sunni Islam	Shia Islam (Twelver)
Infallible Persons	Prophets only	Prophets, Fatimah, 12 Imams
Scope	Only in conveying revelation	In all actions and thoughts
Errors in Daily Life?	Yes	No
Authority after Muhammad	Scholars (fallible)	Imams (infallible)

❗ Shia Dilemma:

The 12th Imam (al-Mahdi) is said to be alive but in occultation since 874 CE. If humanity always needs an infallible guide — why has one been absent for over 1,100 years?

That nullifies the whole point of the doctrine.

4️⃣ Logical and Moral Breakdown: Why ʿIsmah Fails Reason

❌ A. Moral Agency Is Eliminated

If prophets can’t sin, then:

• They don’t choose righteousness — they’re programmed.

• Their actions aren’t virtuous but automatic.

Moral integrity only exists where error is possible but resisted. ʿIsmah erases the moral weight of obedience.

---

❌ B. Circular Reasoning

Muslim theologians argue:

“They’re infallible because God only chooses the purest and most perfect.”

This is circular. You’re assuming they’re perfect to prove they’re perfect.

There is no external evidence for this — just theological necessity dressed as doctrine.

---

❌ C. Infallibility = Immunity from Accountability

By declaring someone infallible:

• Every action they do becomes “good” by definition.

• Even questionable behavior (child marriage, war crimes, sex slavery) becomes untouchable.

• Criticism is heresy, not analysis.

This doctrine is not spiritual — it is political. It converts divine messengers into absolutist authorities.

🧱 Summary: The Collapse of ʿIsmah

Test	Result
Qur’anic Test	❌ Failed (prophets err)
Historical Test	❌ Failed (Satanic Verses)
Logical Test	❌ Failed (removes moral agency)
Moral Test	❌ Failed (justifies unethical actions)

✅ Conclusion:

The doctrine of ʿIsmah is not revealed — it’s reverse-engineered.
It was created to defend theology, not derived from divine truth.

It collapses under the weight of:

• Scripture

• History

• Logic

• Morality
