The Difference Between a Condition, Pillar, Obligation, and Sunnah

1. A condition is something upon which the prayer’s validity depends but which lies outside the prayer itself and generally precedes it, such as purification, the entrance of the prayer time, and facing the qiblah. Conditions that must continue, such as purification, covering the awrah, and facing the qiblah, must remain throughout the prayer according to one’s ability.
2. A pillar is an essential part within the prayer without which a rakah or the prayer is not valid. Omitting it cannot be corrected by Sujood al-Sahw alone. Examples include bowing and prostration.
3. An obligation is a commanded part within the prayer. According to this classification, deliberately omitting it invalidates the prayer, while forgetting it is corrected through Sujood al-Sahw. An example is the first tashahhud.
4. A Sunnah is a prescribed statement or action that completes the prayer and increases its reward. Omitting it deliberately or forgetfully does not invalidate the prayer, and Sujood al-Sahw is not required for omitting it.

The most important practical distinction is that a pillar is not waived through forgetfulness and Sujood al-Sahw alone cannot replace it, whereas an obligation is waived when forgotten and corrected through Sujood al-Sahw.

The Nine Conditions of Salah

The First Condition: Islam

Prayer is an act of worship that is valid only from a Muslim because acceptance of worship is founded upon faith in Allah and submission to Him.

Allah, the Exalted, says:

{Whoever seeks a religion other than Islam, it will never be accepted from him, and in the Hereafter he will be among the losers.} [Ali Imran: 85].

The Second Condition: Sanity

Sanity is the basis of legal responsibility. Prayer is not valid from someone whose intellect is absent because that person cannot comprehend the intention or what is being said and done.

The Prophet, peace and blessings be upon him, said:

“The pen has been lifted from three: the sleeper until he awakens, the child until reaching puberty, and the insane person until regaining sanity.”

Narrated by Abu Dawud (4403) and authenticated by Al-Albani.

The Third Condition: Discernment

Discernment means that a child understands what is addressed to him, can form an intention, and generally comprehends how prayer is performed. It does not mean that the child has become legally accountable; prayer does not become obligatory until puberty. However, the child is instructed to pray and taught it before puberty so that he grows up observing it.

The preceding hadith about the pen being lifted indicates that prayer is not obligatory for a child until puberty. The validity of a child’s prayer before puberty is connected to discernment. If the child understands prayer, intends it, and performs it properly, the prayer is valid. The child should be taught gradually through example and patience until growing up committed to it.

The Fourth Condition: Purification From Ritual Impurity

The worshipper must be purified from minor ritual impurity through wudu and major ritual impurity through ghusl. If unable to use water or if water is unavailable, the worshipper proceeds to the prescribed tayammum.

Allah, the Exalted, says:

{O believers! When you rise for prayer, wash your faces and your hands up to the elbows, wipe your heads, and wash your feet to the ankles. If you are in a state of major impurity, then purify yourselves. But if you are ill, on a journey, have relieved yourselves, or have been intimate with your spouses and cannot find water, then perform tayammum with clean earth, wiping your faces and hands with it. Allah does not intend to make difficulty for you, but He intends to purify you and complete His favor upon you so that you may be grateful.} [Al-Maidah: 6].

The Prophet, peace and blessings be upon him, said:

“Allah does not accept the prayer of any one of you after ritual impurity occurs until that person performs wudu.”

Agreed upon: Al-Bukhari (135) and Muslim (225).

The Fifth Condition: Removing Physical Impurity

The worshipper must remove any physical impurity that is known and can be removed from the body, clothing, and the part of the prayer place in direct contact with the worshipper. This differs from wudu: wudu removes ritual impurity, while removing physical impurity means removing urine, impure blood, or similar substances themselves.

If someone prays while knowing about an impurity and being able to remove it but does not do so, the prayer is invalid. If the person was unaware of it or forgot it and learned about it only after the prayer, there is recognized scholarly disagreement over whether the prayer must be repeated. The stronger view is that it need not be repeated because the Prophet, peace and blessings be upon him, removed his sandals during prayer when Jibril informed him that they contained something impure, and he continued rather than restarting the prayer.

Abu Said Al-Khudri, may Allah be pleased with him, reported:

“While the Messenger of Allah, peace and blessings be upon him, was praying with his Companions, he removed his sandals and placed them on his left. When the people saw this, they removed their sandals. After the Messenger of Allah, peace and blessings be upon him, completed his prayer, he asked, ‘What caused you to remove your sandals?’ They replied, ‘We saw you remove your sandals, so we removed ours.’ The Messenger of Allah, peace and blessings be upon him, said, ‘Jibril came to me and informed me that there was filth on them.’ He then said, ‘When one of you comes to the mosque, let him inspect his sandals. If he sees filth or something harmful on them, let him wipe it off and pray in them.’”

Narrated by Abu Dawud (650) and authenticated by Al-Albani.

The Sixth Condition: Covering the Awrah

A man covers the area between his navel and knees during prayer. When able, he must also pray in appropriate clothing that covers both shoulders or at least one of them. An adult woman covers her body in prayer except her face when no unrelated man is present. She must cover her hair, neck, forearms, lower legs, and feet. There is well-known disagreement concerning the hands; covering them is preferable, though a number of scholars hold that her prayer remains valid if they are uncovered. If an unrelated man can see her, she also covers her face due to the ruling of hijab before unrelated men.

Allah, the Exalted, says:

{O children of Adam! Dress properly whenever you are at worship. Eat and drink, but do not waste. Surely He does not love the wasteful.} [Al-Araf: 31].

The Prophet, peace and blessings be upon him, said:

“None of you should pray in a single garment with nothing covering the shoulders.”

Agreed upon: Al-Bukhari (359) and Muslim (516).

The Seventh Condition: The Entrance of the Prayer Time

An obligatory prayer is not valid before its time begins. A Muslim must verify the time and must not delay the prayer beyond it without a valid Islamic excuse. Prescribed combining for a traveler, a sick person, or others has its own rulings; when prayers are validly combined, the shared time is a legally permitted time for both prayers.

Allah, the Exalted, says:

{When you have finished the prayer, remember Allah while standing, sitting, and lying on your sides. When you are secure, establish prayer. Indeed, prayer is prescribed for the believers at appointed times.} [An-Nisa: 103].

The Eighth Condition: Facing the Qiblah

Someone capable of doing so faces the Ka'bah during prayer and strives to determine its direction. What a person is genuinely unable to do is waived, such as for a patient unable to turn, someone experiencing intense fear, and voluntary prayer upon a mount during travel, which has special rulings established in the Sunnah.

Allah, the Exalted, says:

{Indeed, We see you turning your face toward heaven. We will surely turn you toward a qiblah that pleases you. So turn your face toward the Sacred Mosque. Wherever you may be, turn your faces toward it. Those who were given the Scripture certainly know that this is the truth from their Lord. Allah is never unaware of what they do.} [Al-Baqarah: 144].

The Ninth Condition: Intention

The worshipper intends in the heart the prayer being performed, such as Dhuhr or Asr, whether obligatory or voluntary. The place of intention is the heart, and verbalizing it is not prescribed. It has not been reported that the Prophet, peace and blessings be upon him, or his Companions would say before prayer, “I intend to pray such-and-such prayer.”

The Prophet, peace and blessings be upon him, said:

“Actions are judged only by intentions, and every person will have only what was intended. Whoever emigrated for worldly gain or to marry a woman, then the emigration was for that for which the person emigrated.”

Agreed upon: Al-Bukhari (1) and Muslim (1907).

The Fourteen Pillars of Salah

Prayer is not valid without these pillars, and an omitted pillar cannot be corrected by Sujood al-Sahw alone:

1. Standing when able during an obligatory prayer: someone unable to stand prays according to ability. Imran ibn Husayn, may Allah be pleased with him, reported: “I suffered from hemorrhoids, so I asked the Prophet, peace and blessings be upon him, about prayer. He said, ‘Pray standing. If you cannot, then sitting. If you cannot, then on your side.’” Narrated by Al-Bukhari (1117).
2. The opening takbir: saying “Allahu Akbar” when entering the prayer. The prayer does not begin without it. The Prophet, peace and blessings be upon him, said: “The key to prayer is purification, its sacred state begins with the takbir, and it ends with the taslim.” Narrated by Abu Dawud (61) and authenticated by Al-Albani.
3. Reciting Al-Fatihah in every rakah for the imam and someone praying alone. The stronger view is that it is also obligatory for the follower, though it is waived if the follower joins the imam while he is bowing, forgets it, is unaware of its ruling, or cannot complete it before the imam bows because following the imam is obligatory. This is an area of well-known disagreement among jurists. The Prophet, peace and blessings be upon him, said: “There is no prayer for one who does not recite the Opening of the Book.” Agreed upon: Al-Bukhari (756) and Muslim (394).
4. Bowing.
5. Rising from bowing and standing upright.
6. Prostrating upon seven body parts: the forehead together with the nose, both palms, both knees, and the ends of both feet. The Prophet, peace and blessings be upon him, said: “I have been commanded to prostrate upon seven bones: the forehead,” and he pointed to his nose, “the hands, the knees, and the ends of the feet, and not to gather up the clothing or hair.” Agreed upon: Al-Bukhari (812) and Muslim (490).
7. Rising from prostration.
8. Sitting between the two prostrations.
9. Tranquility in every pillar: merely touching the posture of bowing or prostration is insufficient. The limbs must settle for enough time to fulfill the pillar.
10. Maintaining the proper order of the pillars by performing them according to the Prophetic description; one does not, for example, prostrate before bowing.
11. The final tashahhud.
12. Sitting for the final tashahhud.
13. Sending salah upon the Prophet, peace and blessings be upon him, during the final tashahhud. It is a pillar according to this classification, though scholars differ over its classification. It should never be deliberately omitted.
14. The two salams: saying to the right and then the left, “As-salamu alaykum wa rahmatullah.” The prayer ends with the salam. Both salams are pillars according to the classification presented here, which a number of verifying scholars preferred because the Prophet, peace and blessings be upon him, consistently performed both. Most jurists hold that the first salam is the pillar and the second is a Sunnah, so the worshipper should not deliberately omit the second.

Among the most comprehensive hadiths explaining the prayer’s pillars is the hadith of the man who prayed incorrectly. Abu Hurayrah, may Allah be pleased with him, reported that the Prophet, peace and blessings be upon him, told him:

“When you stand for prayer, say the takbir. Then recite whatever is easy for you from the Quran. Then bow until you are tranquil in bowing. Then rise until you are standing upright. Then prostrate until you are tranquil in prostration. Then rise until you are tranquil while sitting. Do this throughout your entire prayer.”

Agreed upon: Al-Bukhari (757) and Muslim (397).

The hadith establishes the takbir, recitation, bowing, standing upright, prostration, sitting between the two prostrations, tranquility, and proper order.

The Eight Obligations of Salah

The obligations according to the classification followed in this article are:

1. All transitional takbirs other than the opening takbir.
2. Saying “Subhana Rabbiyal-Azim” once while bowing. Anything beyond that is a Sunnah.
3. Saying “Sami Allahu liman hamidah” for the imam and one praying alone. According to this view, the follower does not say it.
4. Saying “Rabbana wa lakal-hamd” for the imam, follower, and one praying alone.
5. Saying “Subhana Rabbiyal-Ala” once in prostration. Anything beyond that is a Sunnah.
6. Saying “Rabbighfir li” once between the two prostrations.
7. The first tashahhud.
8. Sitting for the first tashahhud.

Among the evidence for the remembrances of bowing and prostration is Hudhayfah’s description, may Allah be pleased with him, of the Prophet’s prayer, peace and blessings be upon him:

“I prayed with the Prophet, peace and blessings be upon him, one night. He began Al-Baqarah, and I thought he would bow at one hundred verses, but he continued. I thought he would recite it in one rakah, but he continued. I thought he would bow upon completing it, but then he began An-Nisa and recited it, then began Ali Imran and recited it. He recited slowly. When he passed a verse containing glorification, he glorified Allah; when he passed a verse containing a request, he asked; and when he passed a verse seeking refuge, he sought refuge. Then he bowed and began saying, ‘Subhana Rabbiyal-Azim.’ His bowing was approximately as long as his standing. Then he said, ‘Sami Allahu liman hamidah,’ and stood for a long time, nearly as long as he had bowed. Then he prostrated and said, ‘Subhana Rabbiyal-Ala.’ His prostration was nearly as long as his standing.”

Narrated by Muslim (772).

Among the evidence that omitting the first tashahhud is corrected through Sujood al-Sahw is the report of Abdullah ibn Malik ibn Buhaynah, may Allah be pleased with him:

“The Prophet, peace and blessings be upon him, led them in Dhuhr prayer. He stood after the first two rakahs without sitting, and the people stood with him. When he completed the prayer and the people waited for him to pronounce the salam, he said the takbir while seated and performed two prostrations before the salam, then pronounced the salam.”

Agreed upon: Al-Bukhari (829) and Muslim (570).

Those who adopt this classification cite the Prophet’s not returning to the first tashahhud after standing and his correcting its omission through Sujood al-Sahw as evidence that it is an obligation rather than a pillar.

The Sunnahs of Salah

The Sunnahs of prayer are numerous and include:

1. The opening supplication.
2. Seeking refuge with Allah before recitation.
3. Raising the hands with the opening takbir, when bowing, when rising from bowing, and when standing after the first tashahhud.
4. Placing the right hand over the left while standing.
5. Saying “Amin” after Al-Fatihah.
6. Reciting a surah or verses after Al-Fatihah in the first two rakahs.
7. Saying the glorification more than once during bowing and prostration.
8. Saying more than “Rabbighfir li” between the two prostrations and making authentically established supplications.
9. Supplicating during prostration and after the final tashahhud before the salam.
10. The established sitting postures, placement of the hands, and pointing with the index finger in the reported manner.

Omitting a Sunnah does not invalidate the prayer, but maintaining the Sunnahs completes one’s following of the Prophet, peace and blessings be upon him. A Muslim should not call everything to which one is accustomed a pillar or obligation without evidence.

What Happens When a Condition of Salah Is Missing?

If a condition of prayer is missing despite knowledge and ability, the prayer is invalid. Whoever deliberately prays before the time, without purification, or facing away from the qiblah despite being able to meet the condition must repeat the prayer.

A person unable to fulfill a condition does what is possible because Allah, the Exalted, says:

{So be mindful of Allah to the best of your ability, hear and obey, and spend in charity; that is better for yourselves. Whoever is protected from the selfishness of the soul, it is they who are successful.} [At-Taghabun: 16].

Every excuse has its own rulings. A Muslim does not abandon prayer because of inability to fulfill some conditions, but prays according to ability and asks qualified scholars about the particular situation.

What Should Someone Do After Omitting a Pillar?

1. If it was deliberately omitted, the prayer is invalid.
2. If the omitted pillar was the opening takbir, the prayer never began and Sujood al-Sahw cannot correct it.
3. If a pillar was forgotten and remembered before reaching its place in the following rakah, the worshipper returns to it, performs it and everything after it, and then performs Sujood al-Sahw.
4. If the worshipper reaches the same pillar in the following rakah, the following rakah takes the place of the deficient one according to a number of scholars. The rakah in which the pillar was omitted is disregarded, the prayer is completed, and Sujood al-Sahw is performed.
5. If it is remembered only after the salam, and only a short time has passed, the worshipper returns and completes what is required according to the pillar’s place. If a long interval has passed or wudu has been nullified, repeating the prayer may be required.

The details of correcting omitted pillars may differ according to the pillar and when it is remembered. Someone who forgets a bowing or prostration and does not know how to continue should ask a trusted scholar and must not rely upon Sujood al-Sahw alone, because Sujood al-Sahw does not replace a pillar.

What Should Someone Do After Omitting an Obligation?

1. If it was deliberately omitted while knowing the ruling, the prayer is invalid according to this classification.
2. If it was forgotten, the worshipper continues the prayer and corrects the omission through Sujood al-Sahw.
3. If it is remembered before leaving its position, the worshipper performs it, and in principle nothing else is required.
4. If the first tashahhud is forgotten and remembered before standing fully upright, the worshipper returns, sits, and recites the tashahhud. According to a number of scholars, Sujood al-Sahw is performed if the worshipper had begun rising. Whether prostration is obligatory before standing fully upright involves detail according to how far the person had risen.
5. If the worshipper has stood fully upright, the person does not return, but completes the prayer and performs Sujood al-Sahw before the salam.

For more detail, see Sujood al-Sahw: Before or After Salam?.

What Should Someone Do After Omitting a Sunnah?

Omitting a Sunnah does not invalidate the prayer, and Sujood al-Sahw is not required merely for omitting one. If someone forgets the opening supplication, does not recite a surah after Al-Fatihah, or does not raise the hands at the established places, the prayer is valid.

The worshipper does not return to a Sunnah after its place has passed if returning would disrupt the prayer’s order. For example, after beginning Al-Fatihah, one does not return to the opening supplication.

Rulings for the Imam, Follower, and Person Praying Alone

In principle, pillars are not waived for an imam, follower, or person praying alone. If a follower forgets an obligation while following the imam, the imam generally carries it on the follower’s behalf, and the follower does not perform Sujood al-Sahw independently as long as no part of the prayer was missed.

A latecomer who stands to complete missed rakahs is treated as a person praying alone regarding any forgetfulness occurring in the portion being completed. Reciting Al-Fatihah behind the imam, joining while the imam is bowing, or missing a pillar with the imam involve recognized details about which qualified scholars should be asked when they occur.

Common Mistakes

1. Believing that Sujood al-Sahw corrects every deficiency, even an omitted pillar.
2. Verbalizing the intention before the opening takbir.
3. Confusing removal of physical impurity with purification from ritual impurity.
4. Counting the opening supplication or a surah after Al-Fatihah among the pillars.
5. Rushing through bowing and prostration until tranquility is lost.
6. Abandoning prayer entirely because one cannot stand or face the qiblah, although the obligation is to pray according to one’s ability.
7. Repeating prayer because of a passing doubt or obsessive thought without certainty.
8. Presenting one juristic list as though every detail in it were unanimously agreed upon.
