Madhab: the four Sunni schools and why they differ

What a madhab is, the four Sunni schools and their imams, the six causes of difference Ibn Rushd gives, and one real difference, the intention in wudu, from each school's own book.

By Haroon AliSources checked 28 October 2026

We explain and attribute; we do not issue fatwas.

The short answer

A madhab is the view a jurist or school holds, in Ibn Rushd's usage 3. Ibn Juzayy's al-Qawanin al-Fiqhiyyah names four imams as leaders of Muslims across the lands, each with followers 2. Their schools are the Hanafi, Maliki, Shafi'i and Hanbali. Ibn Rushd's Bidayat al-Mujtahid shows them differing on whether intention is a condition of wudu (ablution) 3. We report each school from its own book.

What does madhab mean?

Madhab, also spelt madhhab, comes from the Arabic root dh-h-b, to go. Ibn Manzur's dictionary Lisan al-Arab gives al-madhhab as a verbal noun of going, like al-dhahab, and as the view a person holds and goes by 4.

In the jurists' books the word names a scholar's position. Ibn Rushd, in Bidayat al-Mujtahid, writes that holding the intention to be a condition of wudu is the madhhab of al-Shafi'i, Malik and Ahmad, as well as Abu Thawr and Dawud 3. Here the word names the view a jurist or school holds.

Who are the four imams of the Sunni schools?

Ibn Juzayy, a Maliki scholar, writes in al-Qawanin al-Fiqhiyyah that by "the four" he means Malik, al-Shafi'i, Abu Hanifah and Ibn Hanbal, and calls them leaders of the Muslims across the lands, each with followers 2. His own book follows Malik's school, which he says the people of al-Andalus and the rest of the Maghrib (the western Islamic lands) chose, and notes where the other three agree and differ 2.

The four imams Ibn Juzayy names, and the book cited for each school
SchoolNamed by Ibn JuzayyBook cited here
HanafiAbu Hanifah al-Nu'man ibn Thabital-Marghinani, al-Hidayah
MalikiMalik ibn AnasIbn Juzayy, al-Qawanin al-Fiqhiyyah
Shafi'ial-Shafi'ial-Nawawi, Minhaj al-Talibin
HanbaliAhmad ibn HanbalIbn Qudamah, al-Mughni

The books cited for each school are by scholars of that school, not by the four imams themselves. So a school's position here is its teaching as those scholars wrote it down.

Why do scholars reach different rulings?

In the introduction to Bidayat al-Mujtahid, Ibn Rushd says his aim is to record the rulings that are agreed on and those that are disputed, with their evidence, and to point out where each disagreement turns 5. He then gives six kinds of cause for the jurists' disagreement 5.

Ibn Rushd's six causes of disagreement (the short labels are ours)
CauseWhat Ibn Rushd describes
1. The reach of a wordA word may be general or particular, and meant as either; it may or may not carry an implied contrary sense.
2. A word with more than one meaningThe word qur' can mean the periods of purity or menstruation; a command may mean obligation or recommendation, and a prohibition forbidding or disliking.
3. GrammarDifferent readings of a word's grammatical ending (i'rab).
4. Literal or figurativeWhether a word is taken in its literal sense or in a figurative one.
5. Unrestricted or restrictedA word left open in one text and qualified in another, such as freeing a slave, qualified in one text as a believing slave.
6. ConflictTwo texts, acts, approvals or analogies that point different ways, or one of these against another.

Every cause on his list is about how the same texts, acts and analogies are read.

Is the intention part of wudu? A worked example

Start with what is shared. 'Umar ibn al-Khattab, may Allah be pleased with him, said from the pulpit that he heard the Prophet Muhammad, peace be upon him, say that actions are only by intentions, and each person has what he intended. The report is Sahih al-Bukhari 1, sahih by inclusion in Sahih al-Bukhari

1AuthenticSahih al-Bukhari 1

.

إِنَّمَا الأَعْمَالُ بِالنِّيَّاتِ، وَإِنَّمَا لِكُلِّ امْرِئٍ مَا نَوَى

Ibn Rushd reports that the jurists agree intention is a condition in acts of worship, for this hadith and for Al-Bayyinah 98:5 (surah 98, verse 5), and then differ on whether it is a condition of valid wudu 3.

وَمَآ أُمِرُوٓا۟ إِلَّا لِيَعْبُدُوا۟ ٱللَّهَ مُخْلِصِينَ لَهُ ٱلدِّينَ حُنَفَآءَ وَيُقِيمُوا۟ ٱلصَّلَوٰةَ وَيُؤْتُوا۟ ٱلزَّكَوٰةَ ۚ وَذَٰلِكَ دِينُ ٱلْقَيِّمَةِ

Al-Bayyinah 98:5And they are ordered nothing else than to serve Allah, keeping religion pure for Him, as men by nature upright, and to establish prayer and to pay the poor-due. That is true religion.

اخْتَلَفَ عُلَمَاءُ الْأَمْصَارِ هَلِ النِّيَّةُ شَرْطٌ فِي صِحَّةِ الْوُضُوءِ أَمْ لَا

In English: the scholars of the cities differ on whether intention is a condition of the validity of wudu or not.

Is the intention part of wudu? One book from each school, in its own words
School and bookWhat the book says
Hanafial-Marghinani, al-Hidayah 1/16SunnahThe base text says it is recommended to intend purification. Al-Marghinani comments that intention in wudu is a sunnah in his school, and reports al-Shafi'i as holding it fard. 6
MalikiIbn Juzayy, al-Qawanin al-Fiqhiyyah p. 19Obligation (fard)Intention is the first of the six obligations of wudu. Ibn Juzayy says it is required in wudu and ghusl (the full ritual wash) for Malik and al-Shafi'i, unlike Abu Hanifah. 7
Shafi'ial-Nawawi, Minhaj al-Talibin p. 12Obligation (fard)The obligations of wudu are six, and the first is the intention, joined to the start of washing the face. 8
HanbaliIbn Qudamah, al-Mughni 1/82Condition (shart)Intention is a condition of purification from every kind of ritual impurity: no wudu, ghusl or tayammum is valid without it. 9

The cause, in Ibn Rushd's account, is this. Pure worship, done only to draw near to Allah, like prayer, needs intention by agreement; worship whose purpose is plain, like washing off dirt, does not. Wudu has something of both, worship and cleanliness, so the jurists differ over which it resembles more 3.

Each school's book argues its own side. Al-Marghinani's al-Hidayah answers that wudu becomes an act of drawing near to Allah only with intention; even so, it is still the key to prayer, because it is purification by using something that purifies 6. Ibn Qudamah's al-Mughni answers with the hadith of 'Umar, and with the point that wudu is worship, and worship is only done with intention 9.

We do not decide between them. The steps themselves, with each school's status at the intention step, are in the guide to how to perform wudu.

Which madhab is closest to the Sunnah?

Ilmwell does not rank the four schools. A more useful question is which evidence supports a particular ruling, and the books cited here answer that for their own view. In the wudu example, al-Marghinani's al-Hidayah and Ibn Qudamah's al-Mughni each set out the evidence for their school, and Ibn Rushd's Bidayat al-Mujtahid puts the positions side by side with the cause of the difference 693.

On whom to ask, al-Ghazali, in al-Mustasfa, says a layperson asks only someone known for knowledge and uprightness, not someone known for ignorance or wrongdoing 10. For a question about your own case, see what a fatwa is, and for how fiqh relates to Sharia, see Sharia law explained.

I grew up in a Hanafi family and did not know much about the other schools until a friend prayed slightly differently next to me. I asked him afterwards, a bit too bluntly, if he was doing it wrong. He was very patient, and it started a long conversation.

Try it: four quick questions

Four quick checks, each with its source.

  1. 1What does Ibn Rushd say the jurists agree on before they differ over wudu?

    Answer: That intention is a condition in acts of worship. He reports agreement that intention is a condition in acts of worship, then a difference over whether it is a condition of valid wudu. Source 3

  2. 2Which school does al-Hidayah, the book that calls intention in wudu a sunnah, belong to?

    Answer: Hanafi. Al-Marghinani writes that intention in wudu is a sunnah "with us", the Hanafis. Source 6

  3. 3How many kinds of cause for disagreement does Ibn Rushd list in his introduction?

    Answer: Six. From the reach of a word to conflict between texts. Source 5

  4. 4Which Arabic idea is the word madhab built on?

    Answer: Going. Lisan al-Arab lists al-madhhab under the root dh-h-b, to go: the view a person goes by. Source 4

Questions people ask

Do I have to follow one madhab?

The books cited for this comparison do not settle that question for a reader. Al-Ghazali's al-Mustasfa says a layperson asks someone known for knowledge and uprightness, not someone known for ignorance or wrongdoing. For your own situation, ask a scholar you trust.

Do the four schools use the same sources?

In the wudu example, Ibn Rushd reports that the jurists agree intention is a condition in acts of worship, citing Al-Bayyinah 98:5 and the hadith that actions are only by intentions (Sahih al-Bukhari 1, graded sahih). They differ on whether intention is a condition of valid wudu, and Ibn Rushd puts the difference down to wudu resembling both worship and cleansing.
