The Zahiri School of Law

1What does "zahir" mean?

The Arabic word zahir means "apparent", "visible", "what lies on the surface". The Zahiris – the "people of the apparent" (Ahl al-Zahir) – received this name because they wanted to understand the texts of the Quran and Sunnah according to their clear, apparent wording. When Allah commands something, it is commanded; when He forbids something, it is forbidden; and where the texts are silent, they did not want to speak with their own conjectures.

Behind this attitude lies a deep reverence for the word of Allah. The Zahiris liked to recall the verse: "This day I have perfected for you your religion" 5:3, and the command: "And do not pursue that of which you have no knowledge" 17:36. For them, the religion was complete, and the scholar's task was to pass it on faithfully – not to add to it from his own reasoning.

2Dawud al-Zahiri – the founder

The founder of the school is Dawud ibn Ali ibn Khalaf, may Allah have mercy on him, also known as Dawud al-Isfahani because his family came from Isfahan. He lived and taught in Baghdad, in the same city and in the same great era in which Imam Ahmad ibn Hanbal was active, and he died there in the year 270 after the Hijra (884 CE).

Dawud studied with leading scholars of his time, among them Ishaq ibn Rahawayh and Abu Thawr. At first he followed the method of Imam al-Shafi'i, whom he greatly admired – it is reported that he wrote a book on al-Shafi'i's virtues. Al-Shafi'i had taught that law must be founded on firm texts and that one may not judge by mere personal preference. Dawud took this path one step further: he became convinced that analogy (qiyas), too, was not a secure foundation for the law of Allah. What Allah and His Messenger ﷺ had said was sufficient.

Dawud was known for his piety, his simple way of life and his sharp intellect. Many students came to him, and in the decades after his death his school had followers and judges in Baghdad and in the eastern lands of Islam. Sadly, his own books have been almost entirely lost; we know his views mainly through later scholars who quote them. His son Muhammad ibn Dawud also became known as a scholar and a poet.

3The Zahiri method

To understand the Zahiri school, it helps to compare its sources with those of the other schools. All schools start from the Quran and the Sunnah. The difference lies in what one does when a case is not explicitly mentioned in the texts.

The Zahiris recognised the following foundations:

1. 1The Quran – according to its apparent wording.
2. 2The authentic Sunnah of the Prophet ﷺ – even when it comes from a single reliable narrator.
3. 3Consensus (ijma') – but in a narrow sense. Ibn Hazm, for example, held that the consensus of the Companions above all could be established with certainty, because only with them could one truly know that everyone had agreed.
4. 4"Evidence" (al-dalil) – a conclusion that follows directly from the text itself, without adding a new reason. If a text says, for instance, that every intoxicant is forbidden, and a particular drink intoxicates, then it is forbidden – not by analogy, but because it falls directly under the wording.

On the other hand, they rejected:

• analogy (qiyas), in which an unmentioned case is treated like a mentioned one because of a shared underlying reason;
• juristic preference (istihsan) and similar methods, in which a scholar departs from a rule out of considerations of the public good;
• blind imitation (taqlid) of a person without knowledge of the evidence.

And where no text commands or forbids? There, according to Zahiri teaching, original permissibility applies: what Allah has not forbidden is permitted, and an obligation arises only through a text. Allah says: "He has explained to you in detail what He has forbidden you" 6:119. This principle makes the Zahiri school surprisingly broad and generous in many everyday questions.

Why did they reject qiyas?

It would be unfair to describe the Zahiris as people who simply did not want to think. The opposite is true: Ibn Hazm even wrote a book of his own on logic. Their concern was a different one. They feared that if human beings decide for themselves why Allah commanded something and derive new commands from that, they will end up raising their own opinions to the rank of divine law. They preferred to say: "Here Allah has spoken, and here He has remained silent – and His silence is a mercy."

The majority of scholars from the other schools saw it differently. For them, qiyas is a careful, disciplined tool that the Companions themselves used, and which makes it possible to apply the timeless principles of the Shari'ah to new cases. Both sides exchanged their arguments over centuries, respectfully and sometimes passionately. It is precisely this exchange that sharpened Islamic legal thought.

4Ibn Hazm of Córdoba

The best-known scholar of the school is without doubt Abu Muhammad Ali ibn Ahmad ibn Sa'id ibn Hazm, may Allah have mercy on him. He was born in the year 384 after the Hijra (994 CE) in Córdoba, then one of the most brilliant cities in the world, with libraries, mosques and scholars of many disciplines. His father was a high state official, and Ibn Hazm grew up in comfort and surrounded by learning.

But his youth fell in a time of great turmoil, as the caliphate of Córdoba fell apart. Ibn Hazm experienced loss, displacement and insecurity, and perhaps this very experience shaped his seriousness and his search for firm, unshakeable foundations. He first studied according to the Maliki school, which prevailed in al-Andalus, then turned to the Shafi'i method, and finally found his home in the Zahiri way.

Ibn Hazm was a scholar of astonishing breadth. He wrote on law, hadith, theology, history, ethics, logic and even on love. Among his best-known works are:

• al-Muhalla – his great work of law, a commentary on his own shorter work al-Mujalla. For each question he brings the evidence from the Quran and Sunnah, the views of the Companions and the following generation, and the positions of the other schools – and examines them all.
• al-Ihkam fi Usul al-Ahkam – his detailed presentation of legal theory.
• Maratib al-Ijma' – a collection of the questions on which, to his knowledge, there is consensus.
• al-Fisal fi al-Milal wa al-Ahwa' wa al-Nihal – a major work on religions and schools of thought, regarded as one of the early works of comparative religion.
• Tawq al-Hamamah ("The Ring of the Dove") – a subtle book about love and its forms, translated into many languages and still read today.
• al-Akhlaq wa al-Siyar – reflections on character, self-discipline and the healing of the soul.

Ibn Hazm was known for his sharp pen. He could write with great severity against views he considered wrong, and this earned him a good deal of hostility in his lifetime. It is reported that his books were burned in Seville, and that he responded with verses saying that one may burn the paper, but not what it contains – for that he carried in his chest. He eventually withdrew to his family's estate in the region of Niebla, continued teaching there, and died in the year 456 after the Hijra (1064 CE).

Later scholars judged him with a beautiful balance. Al-Dhahabi, for example, honoured Ibn Hazm's immense knowledge and his love of authentic hadith in his biographies, while regretting how harshly he sometimes spoke about the imams of the other schools. This attitude – recognising the good and gently criticising what one sees differently – is a model for all of us.

5Influence in al-Andalus and beyond

In al-Andalus, where the Maliki school shaped life in the courts and mosques, the Zahiri voice was a challenge – but a fruitful one. Ibn Hazm pressed the scholars of his time to ground their rulings in evidence and to study hadith even more closely. His student al-Humaydi later carried his works east to Baghdad.

His influence remained tangible after his death:

• In the era of the Almohads in the Maghreb and al-Andalus, the idea of returning directly to the Quran and hadith for a time also found official support.
• Ibn Rushd (Averroes), the great judge and philosopher of Córdoba, repeatedly cites the views of the "people of the apparent" alongside those of the four major schools in his comparative work of law, Bidayat al-Mujtahid.
• The mystic Ibn Arabi, also from al-Andalus, is often described as inclining towards the Zahiri method in matters of law.
• Ibn Taymiyyah wrote a critical study of Ibn Hazm's Maratib al-Ijma' – which is itself a form of appreciation: one engages so thoroughly only with works that deserve it.

Scholars also long debated whether a dissenting Zahiri view prevents consensus. Some did not count their voice because they rejected qiyas; others insisted that the Zahiris, too, are scholars of the Ummah whose word carries weight. That the question was asked so seriously at all shows how much attention the school received.

6What does this look like in practice?

For a lay person, Zahiri views appear mainly in individual questions. A well-known example: Allah says about fasting in Ramadan: "Whoever among you is ill or on a journey, then an equal number of other days" 2:184. Ibn Hazm read this verse literally and concluded that the traveller must make up the fast even if he fasted during the journey. The majority of scholars understand the verse differently and consider the traveller's fast valid, relying on hadith in which Companions fasted while travelling. Both sides appeal to texts – that is the nature of these discussions.

Sometimes the strict attachment to the wording also led to results that other scholars found surprising and criticised. This, too, belongs to an honest account: every method has strengths and limits, and scholars of the different schools helped one another precisely in recognising those limits.

7Why are there so few Zahiris today?

Today the Zahiri school has very few followers who explicitly identify with it. Historians and scholars mention several reasons:

• A lack of institutions: schools of law survive through teachers, colleges, judges and textbooks passed on from generation to generation. The Zahiris rarely held lasting teaching chairs or judicial offices.
• The rejection of qiyas: without analogy it is harder to build a comprehensive system for the ever-new questions of life.
• The tone of debate: the sharpness of some writings did not always make bridge-building easy.
• Absorption into other schools: many Zahiri insights – such as the emphasis on evidence and the rejection of blind imitation – were taken up by scholars of other schools.

And yet the school has not disappeared. Anyone studying comparative Islamic law today can hardly avoid al-Muhalla: the book preserves countless views of Companions and early scholars that would otherwise be hard to find. Ibn Hazm's works on ethics and love are read outside the field of law as well, and his work on other religions is regarded as pioneering.

8Recognised in the Amman Message

The Amman Message of 2004, endorsed in 2005 by scholars from many countries, explicitly names the Zahiri school among the eight recognised schools of law – alongside the Hanafi, Maliki, Shafi'i, Hanbali, Ja'fari, Zaydi and Ibadi schools. It affirms that no one who follows one of these schools may be declared an unbeliever. That is a powerful sign: a school is not measured by the number of its followers, but by the sincerity with which it seeks to understand the Quran and the Sunnah.

In the United Arab Emirates, too, where the Maliki school has a long tradition, this spirit of the middle way (wasatiyyah) and of respect for all recognised schools prevails.

9What we can learn from the Zahiris

Perhaps the Zahiri school gives us above all a question we should ask ourselves again and again: What is my evidence? It teaches us to take the word of Allah seriously, to love the Sunnah of the Prophet ﷺ, and to be careful when we say something in the name of religion. And it reminds us that Allah's silence about a matter is often an ease for people.

The great scholars of all schools read, quoted, criticised and respected one another. Ibn Hazm studied the Malikis, Ibn Rushd quoted the Zahiris, and scholars of every orientation still read al-Muhalla today. So the heritage of the Ummah is not a field of trenches but a garden of many trees, all drinking from the same spring.

May Allah embrace Dawud al-Zahiri, Ibn Hazm and all the scholars of this Ummah with His mercy, and may He teach us what benefits us and let us benefit from what He has taught us.
