In the Name of Allah---the Most Beneficent, the Most Merciful.
Ibn Taymiyyah’s Most Rational Treatise
Ibn Taymiyyah’s monumental work موافقة صحيح المنقول لصريح المعقول is one of the most important books in the Islamic intellectual tradition on the relationship between reason (ʿaql) and revelation (naql).
It is more commonly known by its shorter title:
درء تعارض العقل والنقل
Darʾ Taʿāruḍ al-ʿAql wa al-Naql
and its full title is:
موافقة صحيح المنقول لصريح المعقول
A close rendering of the full title would be:
“The Harmony of Soundly Transmitted Revelation with Clear Rational Judgment.”
The alternative title Darʾ Taʿāruḍ al-ʿAql wa al-Naql means:
“Repelling the Alleged Conflict between Reason and Revelation.”
1. The central thesis
The fundamental thesis of the book is remarkably simple:
There can be no genuine contradiction between authentic revelation and sound reason.
According to Ibn Taymiyyah, Allah is the Creator both of the human intellect and of the revealed guidance. Therefore, truth cannot ultimately contradict truth.
If someone believes that a Qur’anic verse, an authentic Prophetic hadith, or an established principle of revelation contradicts a rational conclusion, Ibn Taymiyyah argues that one must examine the alleged contradiction rather than immediately sacrificing the revealed text.
The problem, he argues, must lie in one of the premises involved:
the transmitted report may not actually be authentic;
the interpretation of the revealed text may be incorrect;
the supposed rational proof may not actually be rationally certain;
or the apparent contradiction may arise from misunderstanding either side.
Thus, the book is not an attack on reason. Rather, it is an attempt to distinguish genuine reason from speculative philosophical and theological assumptions that are presented as reason.
2. Why did Ibn Taymiyyah write the book?
The intellectual background of the book is crucial.
By Ibn Taymiyyah’s time, Islamic theology had been deeply influenced by debates between:
traditionalists (ahl al-hadith);
theologians (mutakallimūn);
philosophers (falāsifah);
Muʿtazilites;
Ashʿarites;
and other theological schools.
A recurring issue was the question:
What should be done when an apparently rational argument conflicts with an apparent meaning of revelation?
Some theological and philosophical approaches developed the principle that a certain rational proof must take precedence over the apparent meaning of revelation. If necessary, the revealed text would then be interpreted figuratively (taʾwīl).
Ibn Taymiyyah challenges the underlying premise.
His question is essentially:
How can we be certain that the alleged rational proof is genuinely certain before using it to reinterpret revelation?
This becomes one of the major themes of the book.
3. The book's critique of the “reason versus revelation” framework
Ibn Taymiyyah rejects the idea that Islam requires Muslims to choose between two independent authorities:
Reason → one side
Revelation → the other side
Instead, he argues that properly understood, they complement each other.
He makes an important distinction between:
Sound reason
صريح المعقول
and
Speculative or corrupted reasoning
which may merely be presented as rational certainty.
Likewise, he distinguishes between:
Authentic revelation
صحيح المنقول
and reports that are weak, fabricated, or improperly interpreted.
Therefore, the real conflict is not:
Reason vs. Revelation
but rather:
Sound reason and authentic revelation vs. false reasoning and erroneous interpretation.
That distinction is fundamental to understanding the entire book.
4. Ibn Taymiyyah's famous methodological principle
One of the most important ideas developed throughout the work is that:
What is genuinely rational cannot contradict what is genuinely revealed.
This does not mean that every individual human interpretation of reason or revelation will agree.
Human beings make mistakes.
A person can misunderstand:
Therefore, an apparent contradiction does not establish a real contradiction.
This principle allows Ibn Taymiyyah to preserve both:
the authority of revelation
and
the legitimate role of human reason.
5. His criticism of Greek philosophy
A substantial portion of the work engages with the philosophical tradition inherited from Greek thought, particularly the systems associated with figures such as:
Ibn Taymiyyah does not merely dismiss philosophy with the statement that it is “rational.”
Instead, he examines the premises and arguments used by philosophers and theologians.
One of his recurring criticisms is that certain philosophical propositions are treated as demonstratively certain when, in his judgment, they are actually based on disputable premises.
For example, a philosopher may construct a chain of reasoning:
Premise A → Premise B → Premise C → theological conclusion.
Ibn Taymiyyah's strategy is often to return to Premise A and ask:
Is this premise actually certain?
If it is not, then the entire argument cannot be used to establish certainty against revelation.
6. His criticism of taʾwīl
Another major theme is the use of figurative interpretation to resolve alleged conflicts between theology and revelation.
For example, if a theologian believes that a particular divine attribute mentioned in revelation cannot be understood according to its apparent linguistic meaning because of a philosophical or theological principle, he may reinterpret the text.
Ibn Taymiyyah challenges this methodology when the reinterpretation is based upon speculative premises.
His objection is not simply:
“Never interpret anything figuratively.”
Rather, his broader argument concerns when interpretation is justified and what authority determines that interpretation.
He argues that one should not establish a philosophical principle first and then force revelation to conform to it.
7. Revelation itself calls people to reason
An important aspect of Ibn Taymiyyah's argument is that the Qur'an itself repeatedly calls human beings to:
The Qur'anic vocabulary includes expressions such as:
أفلا تعقلون
“Will you not reason?”
أفلا يتدبرون
“Will they not contemplate?”
لقوم يتفكرون
“For people who reflect.”
لقوم يعلمون
“For people who know.”
Therefore, Ibn Taymiyyah does not regard reason as an alien instrument imposed upon Islam from outside.
Rather, reason is itself one of the faculties through which human beings recognize truth.
But reason has to operate correctly.
8. The distinction between reason and rationalism
This is one of the most important distinctions for understanding Ibn Taymiyyah.
He does not say:
“Reason is unreliable.”
His argument is closer to:
Human reasoning is reliable when its premises and method are sound, but a speculative philosophical argument should not automatically be identified with reason itself.
This distinction remains highly relevant today.
A modern person might say:
“Science proves X, therefore this Qur'anic statement must mean something else.”
Ibn Taymiyyah's methodological response would be to ask:
Is the scientific proposition genuinely established?
Is it an empirical fact or a theoretical interpretation?
Are its premises certain?
Does the Qur'anic text actually say what the person claims?
Is the contradiction real or merely apparent?
Have both the scientific and textual arguments been properly understood?
The same methodology can be applied without equating modern science with medieval philosophy.
9. The book's significance for Islamic theology
Darʾ Taʿāruḍ al-ʿAql wa al-Naql is particularly significant because Ibn Taymiyyah attempts to construct a comprehensive critique of a major intellectual assumption:
That revelation must be reinterpreted whenever it appears to conflict with philosophical reason.
His alternative is:
First establish what revelation actually says and what reason actually proves.
Only after both have been properly established can one determine whether there is a contradiction.
And if both are genuinely certain, there cannot be a contradiction.
10. The book is much more than a simple refutation
It would be misleading to describe the work merely as an “anti-philosophy book.”
It is considerably broader.
It deals with questions concerning:
In other words, Ibn Taymiyyah is asking a fundamental epistemological question:
How do human beings know what is true?
And then:
What happens when different claims to knowledge appear to conflict?
His answer gives revelation an indispensable epistemic role while retaining an important place for rational investigation.
11. The title itself summarizes Ibn Taymiyyah's project
The full title:
موافقة صحيح المنقول لصريح المعقول
is especially significant.
It contains two carefully chosen expressions:
صحيح المنقول
Soundly transmitted knowledge
This refers particularly to authentic revelation and properly established transmitted evidence.
صريح المعقول
Clear rational understanding
Not every philosophical proposition qualifies as ṣarīḥ al-maʿqūl.
The word ṣarīḥ is important. Ibn Taymiyyah is concerned with what reason clearly and necessarily establishes, rather than what a particular school merely claims to be rational.
Thus, the title itself expresses his epistemological principle:
Authentic revelation and genuinely clear rational truth are ultimately harmonious.
12. Its place in Ibn Taymiyyah's intellectual legacy
This work should be read alongside Ibn Taymiyyah's other major writings on theology, philosophy and logic.
It represents perhaps his most extensive engagement with the intellectual traditions that had developed in the Muslim world around Greek philosophy and kalām.
It also helps explain why later scholars regarded Ibn Taymiyyah as much more than a jurist.
He was simultaneously:
His approach was rooted in the Qur'an and Sunnah, but he was willing to engage his opponents on their own intellectual terrain.
13. The enduring importance of the book
The enduring value of Darʾ Taʿāruḍ lies in its refusal to accept a simplistic dichotomy:
Either believe in revelation or believe in reason.
Ibn Taymiyyah's position is more nuanced:
Believe in authentic revelation and use sound reason; when an apparent contradiction arises, investigate the alleged contradiction rather than assuming that truth has contradicted truth.
This makes the book particularly important for anyone studying the relationship between:
Qur'an → Sunnah → Reason → Philosophy → Science → Theology
It is essentially an extended defense of the proposition that Islamic revelation does not require intellectual irrationality, and genuine rational certainty does not require abandoning revelation.
In one sentence
موافقة صحيح المنقول لصريح المعقول / درء تعارض العقل والنقل is Ibn Taymiyyah's monumental attempt to demonstrate that authentic revelation and sound reason cannot genuinely contradict one another, and that alleged conflicts usually arise from weakness in transmission, interpretation, premises, or reasoning.
