Wudu rests on elements the four schools unanimously declare obligatory and on elements disputed between pillar and recommendation. This page presents both categories, school by school, drawing on the major sources of each madhhab.
The unanimous points are washing the face, washing the hands to the elbows, wiping part of the head, and washing the feet to the ankles, once each. The disputed points are intention, order, continuity, rubbing, wiping the whole head, the ears, the elbows, and conditions of obligation such as having enough water.
The jurists of the four schools agree on the following. First, the presence of a ritual impurity (hadath) to remove is a condition of the obligation of wudu: one whose wudu is still valid owes no new one. Second, washing the hands to the elbows, wiping the head, and washing the feet to the ankles are obligations, based on the verse of al-Ma'ida and the abundant Sunna.
O you who believe, when you rise for prayer, wash your faces and your hands to the elbows, wipe over your heads and your feet to the ankles.
Surah al-Ma'idah, 6
Third, sound skin must expose the limbs involved: wudu is valid only when water reaches the prescribed surface. Fourth, the washed limb must be outer and sound: both feet, visible and not covered by socks or a splint, fall under washing, as hanafis, malikis, shafi'is and hanbalis agree.
No disagreement exists among the scholars of this community on the obligation of washing the hands to the elbows in wudu; it is a pillar and an obligation. The proof comes from the Book, the Sunna and consensus: "wash your faces and your hands to the elbows" (al-Ma'idah 6). Among the texts stands the hadith of Humran, the freed man of Uthman, describing the Prophet's wudu, peace be upon him, limb by limb, three times each, then his words: whoever performs wudu like mine, then stands and prays two rak'ahs without letting his mind wander, his past sins are forgiven.
He called for water for wudu, washed his palms three times, rinsed his mouth and nose, washed his face three times, his right hand to the elbow three times, then the left likewise, wiped his head, washed his right foot to the ankles three times then the left likewise, then said: I saw the Messenger of Allah perform wudu like this wudu of mine, and he said: whoever performs wudu like mine, then stands and prays two rak'ahs in which he lets nothing enter his mind, his past sins are forgiven.
narrated by al-Bukhari (159) and Muslim (226)
The disputed question is the elbow itself. Abu Hanifa, Malik, ash-Shafi'i and Ahmad in the dominant report include it in the washing, on the words "your hands to the elbows". Zufar among the hanafis, some malikis, and Ahmad in another transmission exclude it. Ibn Rushd explains the disagreement through the ambiguity of the word "to" in Arabic (limit or with) and of the word "hand" (palm only, palm and forearm, or the whole arm). Muslim narrated from Abu Hurayra that the Prophet washed his hands up into the upper arm, the argument of those who include the elbows.
Among the malikis, a second view brings the elbows in by precaution: the obligation is not correctly fulfilled without them, and including them removes the burden of defining a limit. Ibn Rushd concludes that the view excluding them is stronger on the literal indication, and that the view including them is clearer on the meaning of the indicator: the hadith of Abu Hurayra, unless read as a mere recommendation.
Wiping the head is a pillar without disagreement, on the verse, the hadiths of Uthman ("then he wiped his head") and the jurists' consensus. The disagreement concerns the sufficient quantity. Malik and Ahmad in one transmission require the whole head. Abu al-Harith asked Ahmad: what if one wipes part and leaves part? He answered: it suffices him, then added: who can cover the whole head? Ibn Qudama notes that the apparent report of Ahmad for a man is completeness, while a woman suffices with the front of her head, as al-Khallal transmitted, and as Aisha is said to have practiced.
The hanafis in their most famous report fix a quarter of the head; a second transmission says the size of the forelock, a third says three fingers, declared the literal position of the school and the one followed in fatwa in the Zahiria. Ibn Abidin confirms that the quarter is the position relied upon by the later hanafis. Among the malikis, Ashhab says half suffices, Muhammad ibn Maslama two thirds, Abu al-Faraj one third. The shafi'is require a portion to which the name of wiping applies, with no fixed minimum.
As for wiping the whole head, hanafis and shafi'is make it a sunna. The hanafi relies on Abdallah ibn Zayd: the Prophet wiped his head with both hands, going and coming back, and on the report "he performed wudu and wiped his whole head". They declare sinful whoever habitually omits covering the whole head without excuse. The shafi'is recommend the whole head in imitation and to leave the disagreement of those who require it. Al-Qurtubi reports consensus: whoever wipes his whole head has done well and fulfilled what is due.
Hair falling loose from the scalp: hanafis, shafi'is and hanbalis do not include it in the obligation, since it does not share with the head in the wiping, and wiping it does not substitute for wiping the scalp, whether gathered above or left down. If hair descends from its root without leaving the prescribed zone, wiping it suffices, even if the hair beneath is shaved. The malikis require wiping the loosened hair, even when very long, since it remains hair of the head.
The maliki scholar as-Sawi advises women, in wudu, to follow ash-Shafi'i or Abu Hanifa, and in the ritual bath Abu Hanifa: water reaches the skin even if the loosened hair stays dry. As for shaving the head after a valid wudu, the majority of jurists hold that it affects nothing: no fresh wudu. Al-Qarafi reports that no known maliki differs, except Ibn Jarir at-Tabari; the Companions shaved at Mina then descended for tawaf without a single re-wiping being transmitted. Among the hanbalis, Ahmad recommends moistening the shaved head without requiring it; ad-Dasuqi declares weak the view requiring it.
The jurists of the four schools agree that washing both outer, sound, uncovered feet to the ankles once is a pillar. They read the verse through the recitation that imposes washing the feet, not wiping, since both readings were received by the community and the abundant Sunna settles the matter. Forgotten heels: the Prophet saw people whose heels stayed dry and said: "woe to the heels from the fire, complete the wudu".
Woe to the heels from the fire, complete the wudu.
narrated by al-Bukhari (60, 69, 161, 163) and Muslim (240, 241, 242)
The Prophet once performed wudu one wash per limb and said: "this is the wudu of one whose prayer Allah accepts no other way"; Ibn Majah reports it (420), declared weak by Ibn Hajar and al-Albani, yet it serves as proof for those who argue with it: full washing of the feet is a condition of acceptance. Al-Bayhaqi notes the wording "then he washed his feet to the ankles as Allah ordered him" in the hadith of Muslim (832). An-Nawawi and al-Kasani cite the Muslims' consensus on the obligation of washing; Ibn al-Mundhir transmits it from the generality of scholars; al-Mawardi writes that the obligation is washing, not wiping, with all jurists.
The ankles themselves must be washed by the majority; only Zufar excludes them. Ibn Qudama sums the arguments: the warning is earned only by dropping an obligation; "complete the wudu" and the words after washing require covering the whole foot; had wiping been allowed, the Prophet would have indicated it; the verse bound the feet at the ankles as it bound the hands at the elbows, requiring the whole interval.
The malikis, shafi'is and hanbalis make intention an obligation and a condition of validity: wudu without intention is invalid, on the verse "they were ordered only to worship Allah, sincere to Him in religion" (al-Bayyinah 5) and on the hadith "deeds are only by intentions" (al-Bukhari 1). One intends removing the hadath, permitting prayer, tawaf, touching the Quran, or fulfilling the obligation of wudu.
The hanafis make it a sunna. The verse of wudu commands washing and wiping without conditioning intention, and the unrestricted is not restricted without proof; purity comes from the water itself, "water is pure and nothing defiles it", and "We sent down from the sky pure water" (al-Furqan 48). Al-Kasani draws from this that intention is not a condition, and the Bada'i explains that the water's cleanliness works by its nature, the tongue's words being an addition. Al-Juwayni goes further: the Quran never mentions intention in wudu, and wudu was transmitted not as pure worship but as a preparatory means.
Ibn Rushd explains the root of the disagreement: wudu stands between pure worship, empty of rational meaning, and intelligible worship, like washing away filth; pure worship requires intention, intelligible worship does not, and wudu shares both. Ibn al-Mundhir reports the divergent views of an early generation: Shafi'i, Rabia, Malik, Ahmad, Ishaq, Abu Ubayd and Abu Thawr required intention in both, wudu and tayammum; Sufyan ath-Thawri waived it for wudu; al-Awza'i distinguished by the teacher shown.
First view: order is a confirmed sunna, not an obligation; held by the hanafis, the malikis in the famous report, al-Muzani, Ibn al-Mundhir, Abu Nasr al-Bandaniji among the shafi'is, and Ahmad in one transmission. Whoever washes his arms or feet before his face, or wipes his head first, deliberately or by forgetfulness, has valid wudu if he intended purification for prayer. Their argument: the conjunction of the verse does not impose order.
Their narrative support, the hadith of Ibn Abbas describing a reversed order, is declared weak: Ibn al-Jawzi says it does not stand, an-Nawawi declares it weak, and as-San'ani concludes that no sound path reaches it. Malik prefers that whoever reversed his wudu repeat it in the verse's order before praying, without ordering repetition of a prayer already performed. Second view: order is an obligation; held by the malikis in one view, the shafi'is and the hanbalis in the madhhab. The verse places a wiped limb between washed limbs, following Arab custom of grouping then adding for a purpose; the many convergent hadiths always describe ordered wudu, never once the reverse; and a worship of linked acts requires order, as in prayer and hajj.
Continuity (muwala) means washing the limbs in sequence, the first not drying before the next begins. Three views. The first makes it an obligation without qualification: malikis in one view, ash-Shafi'i in the earlier school, hanbalis in the madhhab; proof: the Prophet ordered a man with a dry spot on his foot to repeat wudu and prayer, whereas without continuity washing the spot would have sufficed; the hadith is judged authentic, narrated by Abu Dawud (175).
The second view makes it a sunna: hanafis, malikis in one view, ash-Shafi'i in the madhhab, Ahmad in one transmission; the verse commands washing the limbs however done, and continuity binds no more than in the ritual bath. The third view makes it obligatory with memory and capacity, falling with forgetfulness and real excuse: the famous maliki report and a hanbali view. Ibn Taymiyya prefers it: it is the most apparent and most like the principles of the Law and of Ahmad's madhhab, since proofs of obligation reach only the negligent, not the incapable.
The malikis set two conditions. Memory: whoever interrupts by forgetfulness builds on his wudu and completes it, long gap or short; if he forgets a limb, he washes it and repeats what follows while the body has not yet dried, otherwise he confines himself to the forgotten limb. Capacity: whoever interrupts through non-negligent incapacity, water running short, spilt or seized, waits for water then completes, however long the gap. The negligent man who fetched insufficient water must start again if the gap lasted.
Rubbing (dalk) means running the hand over the limb. The malikis define it: passing the hand over the limb with a moderate motion, even if dirt does not leave, even after pouring the water before it dries. The disagreement: sunna or obligation. The majority, hanafis, shafi'is, hanbalis and malikis in one view, make it a sunna: pouring water on the limb suffices, since the name of washing applies to the flow of water without rubbing, and Allah said "wash"; al-Jassas, the Bahr ar-Ra'iq, the Radd al-Muhtar and an-Nawawi argue so.
The malikis in the famous report and al-Muzani among the shafi'is make it an obligation. Al-Hattab records three maliki views: the famous one is obligation, Malik's view in the Mudawwana, since the named washing requires what realizes it; Ibn Yunus relies on the words reported to Aisha, "rub your body with your hand", located by neither al-Hattab nor an-Nafrawi in a source; Ibn Abd al-Hakam denies the obligation, the name of washing holding without rubbing; a third view obliges it not in itself but to secure the water's arrival, lifting it when water has long stayed, attributed to al-Lakhmi and Abu al-Faraj.
The hanafis, the malikis in the famous report and the shafi'is make it a sunna: one who leaves the ears has valid wudu, on the command "perform wudu as Allah ordered you", wiping the ears not being part of it. Wiping the outside and inside is recommended: al-Miqdam ibn Ma'dikarib describes the Prophet wiping his head and his ears on both sides, inserting his index fingers into the canals (narrated by Abu Dawud, 121, authentic).
The hanbalis, Ibn Maslama and the maliki al-Abahri make it an obligation on the words "the ears are part of the head" (narrated by Abu Dawud, 134, and Ibn Majah, 443 to 445, authentic). As for water: malikis, shafi'is, hanbalis and Abu Hanifa in one transmission recommend fresh water for the ears, other than the head's water, on Abdallah ibn Zayd: he took for his ears water other than that of his head (narrated by al-Hakim, 1/252, and al-Bayhaqi, 313, isnad judged authentic). The hanafis recommend the head's water: the ears belong to the head in ruling, though wiping the ears never substitutes for wiping the head. Ibn Abidin notes fresh water is fine, reported from Abu Hanifa, and the Bahr concludes that residual water suffices with us and not with ash-Shafi'i, fresh water sufficing by agreement.
The hanafis require the whole skin touched by pure water: if a needle-tip space escapes the water, the wudu is invalid. The shafi'is require washing with each limb a contiguous portion that surrounds it; al-Khatib ash-Shirbini formulates it: a contiguous portion encircling the limb. Second condition: removing whatever blocks water from the body; the hanafis and malikis name it: wax, grease, dough, clay, fish skin, dried chewed bread, dried mucus in the nose, persistent eye makeup outside the eye, the scribe's ink. The shafi'is and hanbalis make it a condition too. The shafi'is add that nothing on the limb may alter the water harmfully: ash-Shirwani retains this view, scented gum drying on the hair being the example; ash-Shafi'i writes in al-Umm that whatever blocks water from hair and skin must be removed, while what does not, like braids, stays.
Five further conditions are discussed. Presence of enough pure water: hanafis, malikis, shafi'is in one view and hanbalis in one transmission condition the obligation on it; one with only insufficient water washes what he can and performs tayammum for the rest by the shafi'is and hanbalis, on "or you find no water" (an-Nisa 43); the first group declares partial washing void, since capacity is measured only by sufficient water, while the second view pairs substitute with replaced. The ability to use purifying water is likewise a condition of obligation with the hanafis and malikis: no wudu is owed by the incapacitated, such as the sick man, nor by one lacking water; the hanafis specify that none is owed either by one who lost both hands at the elbows and both feet at the ankles. Time: the hanafis require the prayer time's entry for the obligation, the command being broad at first then narrowed. The shafi'is hold three views on the moment of obligation: at the exit of the impurity, the most apparent by Ibn Hajar al-Haytami; at the time's entry or the intention to rise for prayer, backed by the words "I was only ordered to perform wudu when I rise for prayer"; and both together, the view preferred by an-Nawawi. The hanbalis, on the sound view, make the impurity itself the cause of the obligation. No break of intention: the shafi'is require absence of anything cutting intention, apostasy, a mental condition, or interruption mid-wudu, which would need a fresh intention for the rest. Flowing: the shafi'is require water to flow over the limb, mere touch not being named washing. Finally, wudu is not valid with water whose use is forbidden, such as usurped water; a transmission from Ahmad holds it valid, but with disapproval.
As for the person with a permanent excuse, one suffering continuous flow, menstrual, urinary or gaseous: shafi'is and hanbalis require her or him to enter the prayer time, even by supposition, since such purification is bound to time like tayammum; istinja' must precede it, the shafi'is adding protection and continuities up to the prayer. Wudu before the time remains valid for all others: Ibn al-Mundhir reports consensus that purification made before the time is complete. One who doubts an impurity while certain of his purity owes no fresh wudu by the majority; the malikis in the famous report impose it, some say as a recommendation.
In practice, perform wudu in the verse's order, with reasonable continuity, intending to remove impurity, letting water cover the whole face, the hands to the elbows, the feet to the ankles, plus wiping the whole head and the ears: this satisfies both the unanimous obligations and the strictest recommendations of the four schools, and guards the edge cases without falling into excess.
