Introduction
Imagine a magnificent ship, built to sail for centuries. Its hull is strong, its compass true. But the seas change. New storms arise. Uncharted waters appear. The ship needs a captain who can navigate—not by inventing a new compass, but by applying the principles of navigation to waters never before crossed.
That captain is Ijtihad. That navigation is Qiyas.
In Islamic legal terminology, Ijtihad means “the process of deriving the laws of the Shari’ah from its sources.” It is derived from the Arabic word jahada, which means “to strive” or “to attempt.” The process which makes the legal system of Islam dynamic and developed in the changing circumstances through academic research and intellectual effort is termed Ijtihad. The word Ijtihad means to put in the maximum effort to get the solution to a given problem or issue.
Think of it this way: The Quran and Sunnah are the roots. Ijtihad is the branch that grows toward new light. And Qiyas? Qiyas is the method—the careful, logical process of extending existing rulings to new situations.
What is Ijtihad?
Ijtihad is the research on a particular issue, explaining the whole problem by reference to the Quranic verses and the Sunnah of Rasool Allah (PBUH). It is done by Islamic researchers called Mujtahids.
Who can perform Ijtihad?
To perform Ijtihad, a Muslim man or woman should be:
- Thoroughly familiar with the sciences of the Qur’an and the Sunnah
- Able to comprehend the wider purposes of the Shari’ah (Maqasid)
- Fluent in Arabic, understanding its nuances correctly
On complicated and complex issues of law, Ijtihad should be performed by trained scholars. However, any Muslim with some knowledge of religion can perform Ijtihad on certain matters, particularly those of personal concern.
A Beautiful Inclusivity:
Notice something important here. Ijtihad is not reserved only for men. It is not reserved only for scholars in faraway seminaries. Any Muslim—man or woman—with sincere effort and proper knowledge can engage in this sacred intellectual endeavor. Islam empowers minds.
The Necessity of Ijtihad: Proof from Quran and Hadith
Ijtihad is not a human invention. It is an essential element of Islamic law, supported by both the Quran and the Sunnah.
Quranic Evidence
“And when they hear news of security or fear, they publicize it. Had they referred it to the Messenger or their authorities, those with sound judgment among them would have validated it.” — [Surah An-Nisa: 4:83]
This verse recognizes the necessity of independent judgment to arrive at decisions. It tells us that not every matter is explicitly spelled out. Some require “those with sound judgment”—the people who can think, analyze, and derive conclusions.
Hadith Evidence
The most famous proof comes from the story of Mu’adh Ibn Jabal:
The Prophet Muhammad (PBUH), while sending Mu’adh to Yemen as its governor, asked him:
“How will you decide matters coming up before you?”
Mu’adh replied: “I will judge matters according to the Book of Allah.”
The Prophet asked: “But if the Book of Allah contains nothing to guide you?”
Mu’adh said: “Then I will act on the Sunnah of the Prophet of Allah.”
The Prophet asked again: “But if the Sunnah also fails to guide you?”
Mu’adh answered: “Then I will exert to form my own judgment.”
The Prophet (PBUH) approved his answers. — [Abu Dawood 3592]
This is extraordinary. The Prophet did not say, “Wait for revelation.” He did not say, “Ask someone else.” He approved the use of human reasoning when revelation provides no explicit answer. This is the foundation of Ijtihad.

The Importance of Ijtihad
Why does Ijtihad matter? Why can’t Muslims just follow what was written 1,400 years ago?
1. It Makes Islam a Living Tradition
During the life of the Prophet (PBUH), he received divine message directly from Allah, and his life itself was an attempt to concretely apply what the text meant. After his passing, Ijtihad gave room for human beings to interpret the Quran and adapt it to different situations, various problems, and questions as they arise.
Without Ijtihad, Islam would be frozen in the 7th century. With Ijtihad, it speaks to every age.
2. It Emphasizes the Rational Mind
Ijtihad is an intellectual endeavor to seek solutions to day-to-day matters. It has been much emphasized in Islam. It is a rational and analytical approach, based on the Quran and Sunnah, for interpreting religious matters.
The Quran itself calls on people to think:
“And He has subjected to you whatever is in the heavens and whatever is on the earth – all from Him. Indeed, those are signs for people who give thought.” — [Surah Al-Jathiyah: 45:13]
Islam does not ask for blind faith. It asks for informed, reflective, thinking faith.
3. It Requires Wisdom Alongside Revelation
“Do not take Allah’s revelations lightly. Remember Allah’s favors to you, and the fact that He sent down to you the Book and wisdom, for your instruction.” — [Surah Al-Baqarah: 2:231]
This verse shows that the Quran and wisdom are prerequisites to keep society on track and on a progressive and righteous path. The Book has laid down the foundations, but we have to be wise in taking steps to build our lives upon it over time. Wisdom without revelation is unguided. Revelation without wisdom is unapplied. Ijtihad is where they meet.
What is Qiyas? (Analogical Deduction)
Now we move from the broader concept of Ijtihad to one of its most important methods: Qiyas.
Qiyas is the fourth source of Shari’ah, and it is used only when a matter has never been discussed under the three primary sources (Quran, Sunnah, and Ijma). It is a process of deducing a rule from earlier sources.
The Formal Definition
Qiyas is the extension of a Shari’ah ruling from an original case to a new case because the new case has the same effective cause as the original case.
Let me explain with an example:
| Element | Example |
|---|---|
| Original Case (mentioned in Quran) | Wine is prohibited because it intoxicates |
| Effective Cause (illah) | Intoxication |
| New Case (not mentioned in texts) | Cocaine, marijuana, other drugs |
| Qiyas Ruling | They are also prohibited because they share the same cause (intoxication) |
This is not human beings inventing new rules. This is human beings extending divine principles to new circumstances using logical reasoning.
Other Secondary Sources
Qiyas (a form of Ijtihad) is validated by the Quran and Hadith. There are also other sources used in deriving laws:
| Source | Meaning |
|---|---|
| Istihsan | Juristic preference (choosing the better ruling when there are options) |
| Istislah | Public interest (considering what benefits society) |
| Urf | Custom and usage (local traditions that do not contradict Islam) |
These rules were derived by jurists, including the companions of the Prophet (PBUH), and later Muslims through Ijma (consensus).
Comparison: Primary vs. Secondary Sources of Islamic Law
| Aspect | Primary Sources | Secondary Sources |
|---|---|---|
| What they are | Quran and Sunnah | Ijma, Qiyas, Ijtihad, Istislah, Urf |
| Strength | Strong and provide guidance on most issues | Weaker than primary sources; used when primary sources are silent |
| Example | Quran and Sunnah do not discuss modern labor issues—they provide general guidelines | These sources are relevant for deriving rules for socio-economic issues like labor relations and employment |
Think of it this way:
The primary sources are the constitution. The secondary sources are the court rulings that interpret and apply the constitution to specific cases. Both are necessary. Both are valid. But they operate at different levels.

Ijtihad vs. Qiyas: What’s the Difference?
People sometimes confuse these two terms. Here’s the distinction:
| Aspect | Ijtihad | Qiyas |
|---|---|---|
| Meaning | The broader effort of deriving legal rulings | A specific method of deriving rulings |
| Scope | Wide (includes Qiyas, Istihsan, Istislah, etc.) | Narrow (only analogical deduction) |
| Nature | The process itself | One tool within the process |
| Example | A scholar researching a new issue using all available methods | Finding that a new drug is haram because wine is haram for the same reason (intoxication) |
Simple way to remember: Ijtihad is the effort. Qiyas is one of the techniques used within that effort.
Modern Applications of Ijtihad and Qiyas
These are not ancient relics. They are used every day by Islamic scholars and financial institutions.
| Modern Issue | How Ijtihad/Qiyas is Applied |
|---|---|
| Cryptocurrency | Is Bitcoin halal? Scholars compare it to gold (original case) and money (original case) using Qiyas |
| Organ Transplantation | Is it permissible? Scholars use Ijtihad to balance saving life (Quranic value) with bodily integrity |
| IVF and Assisted Reproduction | Scholars use Qiyas to compare IVF to natural conception, then derive rules |
| Islamic Banking | Murabaha, Mudarabah, and other products were developed through Ijtihad |
| Vaccines and Medical Trials | Scholars use Qiyas to extend principles of preserving life to new medical procedures |
The Beauty of Ijtihad
There is something deeply beautiful about Ijtihad. It says to every Muslim: You have a mind. Use it.
Islam is not a religion of blind obedience. It is a religion of informed submission. You submit to Allah, yes—but you submit because you have thought, reflected, and understood. The Quran constantly calls on people to “give thought,” “reflect,” and “use reason.”
Ijtihad is the institutionalization of that call. It is the permission—indeed, the command—to think deeply about how eternal principles apply to changing circumstances.
And the Prophet’s approval of Mu’adh’s method is the eternal green light. When the texts are silent, do not freeze. Do not panic. Think. Exert your effort. And trust that Allah values the sincere seeker, even if they sometimes get it wrong.
The Prophet (PBUH) said:
“If a judge makes Ijtihad and is correct, he receives two rewards. If he makes Ijtihad and is incorrect, he receives one reward.” — [Bukhari & Muslim]
Even the “wrong” answer is rewarded—because the effort itself is worship.
Conclusion
Ijtihad and Qiyas are the engines that keep Islamic law alive, relevant, and just. They are the bridge between 7th century revelation and 21st century reality. They honor the mind without abandoning the heart. They respect tradition without being trapped by it.
The Quran is eternal. The Sunnah is guiding. But the application is ours—through sincere effort, careful reasoning, and humble reliance on Allah.
As the Quran says:
“So ask the people of knowledge if you do not know.” — [Surah An-Nahl: 16:43]
But the asking is not passive. It is the beginning of a journey—a journey of Ijtihad, of Qiyas, of thinking faith.
And that journey never truly ends. Which is exactly as it should be.
