Fiqh of Worship — The How
Step by step, with evidence.
Last updated: April 2026
The Five Pillars page told you what worship is. This page tells you how to do it right. Step by step, condition by condition, with the evidence for each position. Whether you are learning wudu for the first time or finally understanding why you pray qasr when traveling, the mechanics matter because the details are where sincerity meets discipline.
Worship in Islam is tawqifiyyah (restricted to what is legislated). You do not invent a way to pray or decide for yourself how purification works. The method was revealed, demonstrated by the Prophet ﷺ, and transmitted through generations of meticulous scholarship. Every movement, every condition, every exception has a source. That source is what this page opens for you.
This resource presents scholarly positions and evidence for educational purposes. It is not a source of personal fatwas. For rulings specific to your situation, consult a qualified, in-person scholar or a recognized Islamic institution. Differences of opinion in fiqh are a mercy. Follow your qualified teacher.
Wudu (Ablution)
Wudu is the key to salah. No prayer is accepted without it.[1] It is a purification of the body that signals a transition: from the ordinary into the sacred, from distraction into presence. The Prophet ﷺ said that when a Muslim performs wudu and washes his face, every sin he looked at with his eyes comes out with the water; when he washes his hands, every sin his hands committed comes out; when he washes his feet, every sin his feet walked toward comes out, until he emerges purified from sin.[2]
"O you who have believed, when you rise to [perform] prayer, wash your faces and your forearms to the elbows and wipe over your heads and wash your feet to the ankles."
Surah al-Ma'idah 5:6 [Q1]This single ayah contains the four obligatory acts of wudu. Everything else in the procedure is sunnah: recommended, rewarded, but not a condition of validity.
The Obligatory Acts (Fara'id) of Wudu
Scholars differ on the exact number of obligations depending on whether they count intention and sequential order as separate obligations or preconditions. The following represents the position of the majority.[R1]
| # | Obligation | Details |
|---|---|---|
| 1 | Washing the face | From the hairline to the chin, ear to ear. The beard is washed over its surface; running fingers through it is sunnah. |
| 2 | Washing the arms to the elbows | Including the elbows themselves (majority view). Both arms, right then left. |
| 3 | Wiping over the head | At minimum, wiping part of the head. The sunnah is to wipe the entire head from front to back and back to front. |
| 4 | Washing the feet to the ankles | Including the ankles themselves. Water must reach between the toes. |
| 5 | Maintaining the order (tartib) | Hanbali and Shafi'i: obligatory, based on the order in the ayah. Hanafi and Maliki: recommended but not obligatory.[R1] |
| 6 | Continuity (muwalah) | Maliki and Hanbali: obligatory, meaning each limb is washed before the previous one dries. Hanafi and Shafi'i: sunnah.[R2] |
The Complete Sunnah Method
The Prophet ﷺ performed wudu in a specific way that includes the obligations above plus several recommended acts. The following is the full procedure as narrated by 'Uthman ibn 'Affan (may Allah be pleased with him).[3]
What Nullifies Wudu
Wudu is broken by anything that exits from the two private parts (urine, stool, wind), deep sleep in which one loses awareness of themselves, loss of consciousness, touching the private parts directly with the hand (according to the majority based on the hadith of Busrah[12]), and eating camel meat (Hanbali position based on explicit hadith[13]).
Wiping Over Socks (al-Masah 'ala al-Khuffayn)
The Prophet ﷺ wiped over his leather socks (khuffayn) instead of washing his feet. This is established by mutawatir narration. Imam Ahmad said he had no doubt about it, and over forty Companions narrated it.[R1] The ruling extends to thick socks that cover the area of obligation, though scholars differ on the exact conditions.
The permissible period is one day and one night (24 hours) for the resident, and three days and three nights (72 hours) for the traveler. The period begins from the first wipe after the state of purity is broken, according to the stronger opinion.[16]
Ghusl (Full Ritual Bath)
Ghusl is the full-body purification required to lift the state of major ritual impurity (janabah). Without it, salah, tawaf, and touching the mushaf are not permissible. The obligation is established in the Quran:
"And if you are in a state of janabah, then purify yourselves."
Surah al-Ma'idah 5:6 [Q1]When Ghusl is Required
| Cause | Details | Evidence |
|---|---|---|
| Sexual intercourse | Penetration alone requires ghusl, even without ejaculation (by scholarly consensus) | Hadith: "When the two circumcised parts meet, ghusl becomes obligatory."[17] |
| Ejaculation | Emission of mani (sexual fluid) with desire, whether during sleep or wakefulness | Consensus of the scholars[R1] |
| End of menstruation (hayd) | Ghusl is required once bleeding stops before resuming prayer | Surah al-Baqarah 2:222[Q2] |
| End of postpartum bleeding (nifas) | Same ruling as hayd; ghusl when bleeding ceases | Scholarly consensus (ijma')[R1] |
| Death | The deceased Muslim is washed (ghusl al-mayyit) as an obligation on the community | Hadith of Ibn 'Abbas regarding the man who fell from his mount: "Wash him with water and lotus."[18] |
| Embracing Islam | A new Muslim is commanded to perform ghusl upon entering the faith | The Prophet ﷺ commanded Qays ibn 'Asim to perform ghusl when he accepted Islam.[19] |
The Obligatory Minimum of Ghusl
The absolute minimum that makes ghusl valid is two things: intention and ensuring water reaches every part of the body, including the roots of the hair. If a person submerged themselves entirely in water with the intention of ghusl, it would suffice, though it would miss the reward of the sunnah method.
The Sunnah Method of Ghusl
The complete method is narrated by 'A'ishah (may Allah be pleased with her), describing how the Prophet ﷺ would perform ghusl from janabah.[20]
Ghusl is not merely hygiene. It is a return. The state of janabah is not dirt on the skin but a spiritual barrier between you and standing before your Lord. When the water runs over you with intention, you are not just cleaning. You are coming back.
Salah in Detail
Salah is the first act of worship a person will be asked about on the Day of Judgment.[22] If it is sound, everything after it is sound. If it is corrupted, everything after it is corrupted. The prayer has three categories of internal components: pillars (arkan) that cannot be dropped under any circumstance, obligations (wajibat) that require a prostration of forgetfulness if missed, and sunnahs that are rewarded but whose omission does not affect validity.
The Pillars of Salah (Arkan)
A pillar (rukn) is an integral part of the prayer. If it is left out deliberately, the prayer is invalid. If it is left out by forgetfulness, the entire rak'ah in which it was missed must be repeated. Sujud as-sahw (prostration of forgetfulness) alone does not compensate for a missing pillar.[R1]
| # | Pillar | Details |
|---|---|---|
| 1 | Standing (qiyam) | Obligatory in every rak'ah of the obligatory prayer for the one who is able. The one unable to stand prays sitting. |
| 2 | Takbirat al-ihram | The opening "Allahu Akbar." The prayer does not begin without it. It must be said while standing.[23] |
| 3 | Reciting al-Fatihah | In every rak'ah, for both the imam and the one praying alone, according to the majority. The Hanafis consider it obligatory (wajib) rather than a pillar.[24] |
| 4 | Ruku' (bowing) | Bowing until the back is level with the head, hands on the knees. |
| 5 | Rising from ruku' | Returning fully upright after bowing, not rushing through it. |
| 6 | Standing upright after ruku' | Remaining still momentarily in the standing position, with the body at rest (tuma'ninah). |
| 7 | Sujud (prostration) | Prostrating on seven bones: the forehead with the nose, both palms, both knees, and the toes of both feet.[25] |
| 8 | Rising from sujud | Sitting up between the two prostrations. |
| 9 | Sitting between the two prostrations | Sitting upright at rest, not merely lifting the head and going back down. |
| 10 | Tranquility (tuma'ninah) in every pillar | The Prophet ﷺ told the man who prayed badly: "Go back and pray, for you have not prayed." The man's flaw was rushing through the positions without stillness.[26] |
| 11 | The final tashahhud | Sitting for the final testimony of faith (at-tahiyyat). This is a pillar in the final sitting. |
| 12 | Sitting for the final tashahhud | The act of sitting itself is a separate pillar from the words recited during it. |
| 13 | Salawat upon the Prophet ﷺ in the final sitting | Shafi'i and Hanbali: pillar. Hanafi and Maliki: sunnah. Based on the hadith: "Say: Allahumma salli 'ala Muhammad..."[27] |
| 14 | Taslim (saying "As-salamu 'alaykum wa rahmatullah") | Turning right and left with the salam. This ends the prayer. "The key to salah is purification, its opening is the takbir, and its closing is the taslim."[28] |
The Obligations of Salah (Wajibat)
An obligation (wajib) is one level below a pillar. If left out deliberately, the prayer is invalid according to many scholars. If left out by forgetfulness, the prayer remains valid but requires sujud as-sahw (two prostrations before or after the taslim) to compensate. The distinction between arkan and wajibat is primarily a Hanbali classification; the Hanafi school uses "wajib" more broadly.[R1]
| Obligation | Explanation |
|---|---|
| All takbirat other than takbirat al-ihram | Every "Allahu Akbar" said when transitioning between positions (moving to ruku', sujud, standing, sitting). |
| Saying "Sami'allahu liman hamidah" | Said by the imam and the one praying alone when rising from ruku'. |
| Saying "Rabbana wa lakal-hamd" | Said by everyone (imam, follower, and individual) after rising from ruku'.[29] |
| Saying "SubhanAllah Rabbi al-'Adhim" in ruku' | At least once, though three times is the sunnah.[30] |
| Saying "SubhanAllah Rabbi al-A'la" in sujud | At least once, though three times is the sunnah.[30] |
| Saying "Rabb ighfir li" between the two prostrations | At least once.[31] |
| The first tashahhud (in prayers of 3 or 4 rak'ahs) | The sitting and recitation after the second rak'ah. If forgotten, sujud as-sahw compensates for it.[32] |
Sunnahs of Salah
These are acts that bring additional reward. Leaving them does not require sujud as-sahw, and the prayer remains complete without them. But the prayer of the one who observes them is fuller, richer, and closer to how the Prophet ﷺ prayed.
Among the verbal sunnahs: the opening supplication (du'a al-istiftah) after takbirat al-ihram,[33] saying "a'udhu billahi min ash-shaytan ir-rajim" before reciting, saying "ameen" after al-Fatihah, reciting a surah after al-Fatihah in the first two rak'ahs, reciting aloud in Fajr and the first two rak'ahs of Maghrib and 'Isha, and making du'a in sujud and before the taslim.
Among the physical sunnahs: raising the hands with the takbirat al-ihram, when going into ruku', when rising from ruku', and when standing from the first tashahhud;[34] placing the right hand over the left on the chest; looking at the place of prostration; keeping the back level with the head in ruku'; spacing the arms away from the sides in sujud; sitting in iftirash (on the left foot) in the first tashahhud and tawarruk (left foot under right shin) in the final one.[35]
What Invalidates Salah
| Invalidator | Details |
|---|---|
| Deliberate speech | Any speech unrelated to the prayer, if done knowingly and deliberately. Forgetful speech does not invalidate according to the stronger opinion.[40] |
| Deliberate excessive movement | Three or more consecutive movements not part of the prayer, done without necessity. A small movement (scratching, adjusting clothes) does not invalidate. |
| Eating or drinking deliberately | Even a small amount invalidates the prayer if done intentionally. |
| Laughing aloud | A smile does not invalidate, but audible laughter does, by consensus.[R1] |
| Loss of wudu | Any nullifier of wudu occurring during the prayer breaks it immediately. |
| Exposure of the 'awrah | If the covering falls and is not immediately corrected, the prayer is invalid. |
| Deliberately turning away from the qiblah | Turning the chest completely away from the direction of prayer. Slight turns of the head do not invalidate but are disliked.[41] |
| Leaving a pillar or condition deliberately | Deliberately omitting any of the fourteen pillars or knowingly violating a precondition. |
When a person adds something to the prayer by mistake (an extra rak'ah, for example), omits an obligation, or is uncertain about the number of rak'ahs, sujud as-sahw compensates. The Hanbali method: two prostrations before the taslim for omissions, after the taslim for additions. The Hanafi method: always after the taslim. The Shafi'i method: always before the taslim. The Maliki method varies by case.[42] In cases of doubt about the number of rak'ahs, the person builds upon what they are certain of (the lesser number) and performs sujud as-sahw.[43]
The categories of salah are not bureaucracy. They are mercy encoded in law. The pillar cannot be dropped because it is the body of the meeting with your Lord. The obligation can be compensated because forgetfulness is human, and He knows you forget. The sunnah is there for the one who wants more, because He loves the one who draws near through what is not required of them.
The Traveler's Prayer
Travel is a recognized hardship in the Shari'ah, and the prayer is adjusted to accommodate it. Two concessions apply: shortening (qasr) and combining (jam'). Both are established by the Quran, the Sunnah, and scholarly consensus.
"And when you travel throughout the land, there is no blame upon you for shortening the prayer, if you fear that those who disbelieve may attack you."
Surah an-Nisa' 4:101 [Q3]'Umar (may Allah be pleased with him) asked the Prophet ﷺ about this ayah, noting that the condition of fear no longer applied after Islam was established. The Prophet ﷺ replied: "It is a charity that Allah has given you, so accept His charity."[44]
Shortening the Prayer (Qasr)
Qasr means reducing the four-rak'ah prayers (Dhuhr, 'Asr, 'Isha) to two rak'ahs. Fajr and Maghrib are never shortened. The Prophet ﷺ always shortened the prayer when traveling and never prayed four rak'ahs for a shortened prayer during any of his journeys.[45]
| Issue | Ruling | Details |
|---|---|---|
| Minimum distance | Approximately 80 km (48 miles) | Based on the distance used by Ibn 'Abbas and Ibn 'Umar (may Allah be pleased with them). The majority of scholars use this threshold, equivalent to roughly four burud (postal stages).[R1] |
| When it begins | Upon leaving the boundaries of one's city | One does not begin shortening while still within their place of residence. |
| Maximum duration | Debated among scholars | The majority set a limit (most commonly four days, excluding arrival and departure). Some scholars, including Ibn Taymiyyah, hold that there is no fixed limit: one shortens as long as one does not intend permanent settlement.[R5] |
| Ruling | Sunnah mu'akkadah (emphasized sunnah) for the Shafi'i and Maliki schools; obligatory for the Hanafi school | The Hanafis hold that the traveler who prays four rak'ahs has made an error. The majority says it is strongly recommended but valid if prayed in full.[R2] |
Combining Prayers (Jam')
Combining means praying Dhuhr and 'Asr together in the time of either, or Maghrib and 'Isha together in the time of either. The Prophet ﷺ combined prayers during the journey of Tabuk, bringing Dhuhr and 'Asr together and Maghrib and 'Isha together.[46]
The Sick Person's Prayer
The prayer is never dropped as long as a person is conscious and sane. It is the last obligation to be released. The Prophet ﷺ said to 'Imran ibn Husayn (may Allah be pleased with him): "Pray standing; if you cannot, then sitting; if you cannot, then lying on your side."[48]
This hadith establishes the central principle of the sick person's prayer: capability determines the method, and the obligation adjusts to the person's condition, never the other way around. You do not wait until you are well to pray. You pray with whatever you have.
| Level | Condition | How to Pray |
|---|---|---|
| 1 | Able to stand but with difficulty | Stand for as long as possible, then sit for the remainder. Use a wall or stick for support if needed. |
| 2 | Unable to stand | Pray sitting, performing ruku' and sujud as normal if possible. Sit cross-legged or however is comfortable. |
| 3 | Unable to sit | Pray lying on the right side facing the qiblah. If unable to face the qiblah, pray in whatever direction one can manage. |
| 4 | Unable to lie on the side | Pray lying on the back with feet toward the qiblah if possible, using head gestures (ima') for ruku' and sujud. The sujud gesture is lower than the ruku' gesture. |
| 5 | Unable to move the head | Gesture with the eyes or intend the movements in the heart. Some scholars consider prayer obligatory even at this level as long as the mind is sound.[R1] |
The sick person does not combine pillars or skip them merely for convenience. Pain alone does not permit sitting if standing is physically possible. However, if standing would cause significant harm, worsen the condition, or substantially delay recovery, sitting becomes the correct ruling. The standard is genuine inability or genuine harm, not mere discomfort. If a person's condition changes during the prayer (they gain or lose the ability to stand), they transition immediately to whatever they are now capable of, without restarting the prayer.[R1]
"Allah does not burden a soul beyond that it can bear."
Surah al-Baqarah 2:286 [Q4]The fact that the prayer adjusts to you, and never the reverse, tells you something about the One who legislated it. He knows exactly what you carry. He does not ask for more than you have. But He asks for everything you do have. The sick person who gestures with their eyes in prayer may be closer to Him than the healthy person who stands distracted.
The Funeral Prayer (Salat al-Janazah)
The funeral prayer is a communal obligation (fard kifayah): if enough members of the community perform it, the obligation is lifted from the rest. If no one performs it, the entire community is sinful. It is the last act of worship the living perform for the dead before the body is placed in the earth. The Prophet ﷺ said: "Pray over your dead."[49]
Conditions of the Funeral Prayer
The conditions that apply to all prayers apply here: purity, facing the qiblah, covering the 'awrah, and intention. In addition, the body must be present (or in the direction of the qiblah for an absent funeral prayer, which is a matter of scholarly discussion), the body must have been washed (or tayammum performed on it if water is unavailable), and the deceased must be a Muslim. The prayer is performed standing, with no ruku' or sujud.
Who Is Prayed Over
The funeral prayer is performed for every Muslim who dies, including children and newborns who showed signs of life after birth. The stillborn who did not show signs of life is not prayed over according to the majority, but is named and buried. The martyr who dies on the battlefield is not washed or prayed over, following the practice of the Prophet ﷺ with the martyrs of Uhud.[50]
Who Leads the Prayer
The person most entitled to lead the funeral prayer is the one the deceased appointed by will, then the Muslim ruler or his representative, then the deceased's father, then grandfather, then son, then grandson, then closest male relative. Some scholars say the regular imam of the mosque takes precedence. If the deceased was a woman, the same order applies, with her male guardian (wali) leading.[R1]
How It Is Performed
The funeral prayer consists of four takbirat (some narrations mention five, and this is valid), each followed by specific recitations. There is no ruku', no sujud, and no tashahhud.
The Prophet ﷺ prayed the funeral prayer for the Negus of Abyssinia (an-Najashi) in his absence, going out to the musalla and lining up his Companions in rows.[54] The Shafi'i and Hanbali schools permit the absent funeral prayer for any Muslim who dies, while the Hanafi and Maliki schools restrict it to the specific case of the Negus or consider it abrogated. The middle position (held by Ibn Taymiyyah) permits it for a person who was not prayed over in their own locality.[R5]
"Whoever attends the funeral prayer until it is finished will have one qirat of reward. Whoever stays until the burial will have two qirats." They asked: "What are two qirats?" He said: "Like two great mountains."
Narrated by Abu Hurayrah — Sahih al-Bukhari [55]No ruku'. No sujud. Just four words and a supplication. The funeral prayer is the most stripped-down prayer in Islam, because at the threshold of the grave, all that remains is the du'a. You are not performing for the dead. You are begging the Living on their behalf.

Every detail of worship, from the angle of your hands in ruku' to the words whispered in sujud, was prescribed by the One being worshipped. The how is not arbitrary. It is revelation. And following it precisely is itself an act of declaring that only He has the right to tell you how to stand before Him.
