Lesson
1. Ruling and form of prostrations of forgetfulness
بَابُ سُجُودِ السَّهْوِ
سُجُودُ السَّهْوِ وَاجِبٌ فِي الزِّيَادَةِ وَالنُّقْصَانِ بَعْدَ السَّلَامِ، يَسْجُدُ سَجْدَتَيْنِ، ثُمَّ يَتَشَهَّدُ وَيُسَلِّمُ.
Translation: Chapter of prostrations of forgetfulness. In the specified cases of inadvertent addition or omission, two prostrations of forgetfulness are obligatory after salam; one then recites tashahhud and says salam.
Sahw means forgetfulness. Not every incidental movement leads to this prostration: the relevant addition or omission must fall under the defined causes.
In the Hanafi procedure, the two prostrations follow salam at the final sitting, after which tashahhud and salam complete the prayer.
2. Obligatory, but not an integral pillar
In Hanafi law, sujud al-sahw is wajib, not itself a fard pillar. It compensates for specified inadvertent omissions of obligations, but does not replace a missed essential pillar.
If a fard component was omitted altogether, two compensatory prostrations cannot by themselves make that deficient prayer valid.
3. Before or after salam? Juristic differences
The Hanafis generally perform two prostrations after salam, drawing on prophetic reports of prostration following salam.
Shafi‘i jurists generally place them before salam. Maliki law distinguishes omissions from additions: often before salam for omissions, afterward for additions. The difference turns on reconciling varying reliable hadith reports.
4. Tashahhud and salam after the prostrations
After the two prostrations, the prescribed sitting includes tashahhud and salam. This does not require restarting or repeating every previous pillar; the designated pair of prostrations is the compensatory act.
Scholars differ over some subsidiary details of the closing supplications, but the pair of prostrations is the central form.
5. Inadvertent addition of a prayer-type act
وَيَلْزَمُهُ سُجُودُ السَّهْوِ إِذَا زَادَ فِي صَلَاتِهِ فِعْلًا مِنْ جِنْسِهَا لَيْسَ مِنْهَا، أَوْ تَرَكَ فِعْلًا مَسْنُونًا،
Translation: Sujud al-sahw becomes due when someone inadvertently adds an act of the same type as the prayer but not belonging at that point, or omits a prescribed Sunnah-established act of the class that requires compensation.
An addition of the same type means an extra prayer act, such as an unwarranted bow or prostration. A separate kind of action that invalidates prayer must be considered under its own ruling.
The phrase a Sunnah-established act does not mean that every ordinary Sunnah omitted triggers sujud al-sahw; it concerns specifically binding practices established by Sunnah.
6. Distinguishing Sunnah from wajib
Inadvertent omission of a wajib can require sujud al-sahw. Omitting an ordinary Sunnah or recommended act does not by itself do so.
For example, forgetting a routine recommended formula is not equivalent to omitting tashahhud, a separately identified binding obligation.
7. Omitting Fatiha, qunut or tashahhud
أَوْ تَرَكَ قِرَاءَةَ فَاتِحَةِ الْكِتَابِ، أَوِ الْقُنُوتَ، أَوِ التَّشَهُّدَ،
Translation: Or omits recitation of Surat al-Fatiha, the qunut, or the tashahhud.
For Hanafis, some Qur’anic recitation is fard, while specifically reciting Fatiha is wajib; forgetting Fatiha when the underlying recitation was made can require prostration.
Qunut here refers to the wajib qunut of Witr and tashahhud to its prescribed sitting, each in its proper context.
8. Fatiha: Hanafi and Shafi‘i distinction
Hanafi law distinguishes the obligatory minimum Qur’anic recitation from the wajib specification of Fatiha; omission of the latter may require sujud al-sahw.
In Shafi‘i law, Fatiha itself is a pillar of each relevant rakah, so a missed pillar cannot simply be replaced by prostrations. The schools interpret the Qur’anic command and Fatiha-related traditions differently.
9. Eid takbirs and recitation volume
أَوْ تَكْبِيرَاتِ الْعِيدَيْنِ، أَوْ جَهَرَ الْإِمَامُ فِيمَا يُخَافَتُ، أَوْ خَافَتَ فِيمَا يُجْهَرُ.
Translation: Or omits the extra Eid takbirs, or the imam recites aloud where he should recite quietly, or quietly where he should recite aloud.
The extra Eid takbirs are binding in Hanafi prayer; accidental omission falls among causes of prostration. Likewise, when an imam mistakenly reverses the prescribed audible or quiet recitation, compensation is required.
This specifically concerns the imam; a person praying alone has different rules in some prayers.
10. Which omissions or additions trigger compensation?
The established causes can be grouped as:
Addition: an unwarranted prayer-type action.
Omission: forgetting a wajib such as Fatiha, qunut, tashahhud, or Eid takbirs.
Altered performance: the imam reverses the required volume of recitation.
A missing fard pillar or an independent invalidating act follows a different legal rule.
11. The imam’s mistake and the follower
وَسَهْوُ الْإِمَامِ يُوجِبُ عَلَى الْمُؤْتَمِّ السُّجُودَ، فَإِنْ لَمْ يَسْجُدِ الْإِمَامُ لَمْ يَسْجُدِ الْمُؤْتَمُّ،
Translation: The imam’s lapse obliges the follower to follow in the prostrations of forgetfulness. But if the imam does not perform them, the follower does not perform separate prostrations alone.
A follower is linked to the imam. If the imam performs sujud al-sahw, the follower joins even if personally free of error.
If the imam leaves these prostrations, the follower does not separate from him to perform them independently. Other consequences require separate discussion.
12. The follower’s personal lapse
فَإِنْ سَهَا الْمُؤْتَمُّ لَمْ يَلْزَمِ الْإِمَامَ وَلَا الْمُؤْتَمَّ السُّجُودُ.
Translation: If the follower alone lapses, neither the imam nor the follower has to perform prostrations on account of that lapse.
This concerns a lapse while following the imam. It does not impose compensatory prostrations on the congregation.
When a latecomer later completes missed rakahs individually, errors in that separate portion are governed by distinct rules.
13. Forgetting the first sitting
وَمَنْ سَهَا عَنِ الْقَعْدَةِ الْأُولَى، ثُمَّ تَذَكَّرَ وَهُوَ إِلَى حَالِ الْقُعُودِ أَقْرَبُ: عَادَ فَجَلَسَ وَتَشَهَّدَ، وَإِنْ كَانَ إِلَى حَالِ الْقِيَامِ أَقْرَبَ: لَمْ يَعُدْ، وَسَجَدَ لِلسَّهْوِ.
Translation: If one forgets the first sitting and remembers while still closer to sitting, one returns, sits and recites tashahhud. If already closer to standing, one does not return; one performs sujud al-sahw.
The first sitting is wajib in Hanafi law. What matters is the physical stage when the omission is remembered: closer to sitting or closer to standing.
Once near full standing, one does not interrupt the standing to recover the missed wajib; sujud al-sahw compensates.
14. Remembered while still close to sitting
After two rakahs, a person starts rising without the first sitting but is still physically nearer the seated position. The person returns and recites tashahhud.
Because the sitting remains recoverable at that stage, its obligation is fulfilled rather than treating it as a completed omission.
15. Remembered near the standing position
If, after missing the first sitting, the worshipper has reached a position closer to standing, the person should continue rather than return to sitting. Sujud al-sahw is performed at the end.
The reason is that the transition into obligatory standing has substantially begun.
16. Rising to a fifth rakah without final sitting
وَإِنْ سَهَا عَنِ الْقَعْدَةِ الْأَخِيرَةِ، فَقَامَ إِلَى الْخَامِسَةِ: رَجَعَ إِلَى الْقَعْدَةِ مَا لَمْ يَسْجُدْ، وَأَلْغَى الْخَامِسَةَ، وَسَجَدَ لِلسَّهْوِ.
Translation: If one omits the final sitting and rises to a fifth rakah, one returns to the final sitting before performing a prostration of the fifth, disregards the extra rakah, and performs sujud al-sahw.
The final sitting is a pillar in a four-rakah fard prayer. Before prostrating in the unintended fifth rakah, the person can still recover that final sitting by returning.
This differs from the first sitting, which is wajib, not fard.
17. The fifth rakah has not yet been prostrated
If a person rises for an unintended fifth rakah after omitting the final sitting but has not yet prostrated in that fifth, the proper response is to return to the final sitting, disregard the fifth and perform sujud al-sahw.
The obligatory final sitting is still recoverable, so the underlying fard prayer can remain valid.
18. Fifth prostration after omitting the final sitting
وَإِنْ قَيَّدَ الْخَامِسَةَ بِسَجْدَةٍ: بَطَلَ فَرْضُهُ، وَتَحَوَّلَتْ صَلَاتُهُ نَفْلًا، وَكَانَ عَلَيْهِ أَنْ يَضُمَّ إِلَيْهَا رَكْعَةً سَادِسَةً.
Translation: If the fifth rakah is fixed by a prostration, the fard prayer is lost, the prayer turns into a voluntary prayer, and a sixth rakah must be joined to it.
Here the decisive threshold is fixing the fifth rakah with prostration. Without the required final sitting, prostration in the extra fifth prevents completion of the four-rakah fard prayer.
Under this Hanafi ruling, the prayer becomes nafl and a sixth rakah is added; the fard prayer must still be performed.
19. The critical difference: final sitting performed or omitted
The key legal difference is whether the obligatory final sitting occurred:
• Omitted it, then rose for a fifth: return before its prostration; after its prostration, the fard is lost.
• Completed the final sitting, then rose by mistake: the essential sitting was already fulfilled, changing the status of the extra rakah.
20. Completed fourth sitting, then stood for a fifth
وَإِنْ قَعَدَ فِي الرَّابِعَةِ، ثُمَّ قَامَ، وَلَمْ يُسَلِّمْ يَظُنُّهَا الْقَعْدَةَ الْأُولَى: عَادَ إِلَى الْقُعُودِ مَا لَمْ يَسْجُدْ لِلْخَامِسَةِ، وَسَلَّمَ، وَسَجَدَ لِلسَّهْوِ.
Translation: If one sat after the fourth, then rose without salam thinking it was the first sitting, one returns before prostrating in the fifth, says salam and performs sujud al-sahw.
The obligatory final sitting after the fourth was already done. The error here is delayed salam and unintended extra standing, rather than omission of the fard sitting.
Returning before the fifth’s prostration preserves the completed fard prayer, and sujud al-sahw compensates for the addition.
21. Fifth prostration after a completed final sitting
وَإِنْ قَيَّدَ الْخَامِسَةَ بِسَجْدَةٍ: ضَمَّ إِلَيْهَا رَكْعَةً أُخْرَى، وَقَدْ تَمَّتْ صَلَاتُهُ، وَالرَّكْعَتَانِ نَافِلَةٌ.
Translation: If one has fixed the fifth rakah by prostration, one joins another rakah. The fard prayer was already completed, and the two added rakahs count as voluntary.
The fard final sitting had already been fulfilled, protecting the underlying four-rakah prayer. Once the extra fifth includes a prostration, a sixth is added, forming two voluntary rakahs.
Subsidiary discussion includes prostration for delayed salam. The central distinction from the earlier case is completion of the obligatory final sitting.
22. Comparing four fifth-rakah scenarios
1. Final sitting omitted, no fifth prostration: return and perform sujud al-sahw.
2. Final sitting omitted, fifth prostration done: fard is not valid; the prayer counts as nafl, so a sixth is added.
3. Final sitting completed, no fifth prostration: return, say salam and make sujud al-sahw.
4. Final sitting completed, fifth prostration done: add a sixth; four fard are completed and the extra two are nafl.
23. Doubt about the number of rakahs
وَمَنْ شَكَّ فِي صَلَاتِهِ، فَلَمْ يَدْرِ أَثَلَاثًا صَلَّى أَمْ أَرْبَعًا؟ وَذَلِكَ أَوَّلُ مَا عَرَضَ لَهُ: اسْتَأْنَفَ الصَّلَاةَ،
Translation: If one doubts whether three or four rakahs were performed, and it is the first such occurrence, one starts the prayer anew.
First occurrence refers to an unfamiliar incident of uncertainty. The cited ruling is to restart the prayer.
This is distinguished from frequent recurring doubt, where repeatedly restarting is not the intended legal approach.
24. Frequent doubt: follow the stronger judgment
فَإِنْ كَانَ يَعْرِضُ لَهُ كَثِيرًا: بَنَى عَلَى غَالِبِ ظَنِّهِ،
Translation: If such doubt happens repeatedly, one acts upon the stronger judgment.
Predominant judgment means one of two possibilities is more convincingly likely. For example, if the person repeatedly doubts between three and four rakahs but genuinely finds four more likely, that stronger conclusion guides the count.
A random guess does not amount to predominant judgment.
25. No stronger judgment: build upon certainty
وَإِنْ لَمْ يَكُنْ لَهُ ظَنٌّ: بَنَى عَلَى الْيَقِينِ.
Translation: If one has no stronger judgment, one builds on what is certain.
When probabilities are balanced, certainty lies in the smaller established number. Between three and four, three are definite while the fourth is doubtful; the smaller number is the basis for completion.
The ruling preserves established certainty rather than treating a doubtful rakah as proven.
26. Certainty versus predominant judgment
Equal doubt: two possibilities are equally likely.
Predominant judgment: one possibility is more likely, even without certainty.
Certainty: the amount definitively completed.
With recurrent doubt, one first follows a genuine predominant judgment; absent such a judgment, one builds upon certainty and uses the smaller count.
27. Prophetic guidance on prayer doubt
Prophetic reports on prayer uncertainty include two principles: seeking the more likely correct count and building upon certainty when no stronger judgment exists.
These are not contradictory approaches. They govern different conditions of the same problem: actual predominant belief versus unresolved equal doubt.
28. Mistake, doubt and invalidity: three categories
Sahw: forgetting a binding duty or adding an unwarranted prayer act; sujud al-sahw can compensate.
Doubt: uncertainty about rakah count; repeated uncertainty is resolved by stronger judgment or certainty.
Invalidity: missing an essential pillar or adding an act that destroys the fard prayer’s status; two compensatory prostrations cannot repair that by themselves.
29. First sitting and final sitting compared
First sitting: a wajib after the first two rakahs of a four-rakah fard prayer. If forgotten and one approaches standing, do not return; use sujud al-sahw.
Final sitting: an essential pillar after the last fard rakah. Prostrating in an extra fifth without completing it causes loss of the fard status.
This distinction underlies the different fifth-rakah cases.
30. Integrated recap of the causes
Principal causes include forgetting a wajib, adding an unintended prayer-type act, and the imam mistakenly changing obligatory recitation volume.
The imam’s lapse affects the congregation; the follower’s personal lapse during following does not independently require these prostrations.
For sittings and an extra fifth rakah, the key facts are the legal status of the sitting and whether the extra fifth has reached prostration.
31. Application: omitting qunut in Witr
If the Witr qunut is omitted by mistake in the third rakah and the prayer otherwise continues, sujud al-sahw is due because qunut is wajib in Hanafi law.
Omitting a particular recommended wording should not automatically be equated with omitting qunut altogether; the required act and the selected supplication wording have distinct rules.
32. Application: imam recites Maghrib quietly
If an imam accidentally recites quietly in the first two rakahs of Maghrib instead of audibly, the required mode of recitation has been omitted. Sujud al-sahw becomes due, and followers join the imam in those prostrations.
33. Application: four versus five rakahs
When a fifth rakah is mistakenly begun in a four-rakah fard, determine two facts: was the required final sitting completed after the fourth, and has the fifth’s prostration already happened?
Those two facts decide whether to return to sitting, complete two added voluntary rakahs, or repeat the fard due to invalidity.
34. Application: doubt between three and four
Someone doubts whether three or four rakahs have been performed. For a first unusual occurrence, the text gives the ruling of restarting.
For recurrent doubt, follow a genuine stronger judgment; if four is more likely, count four. Without a stronger judgment, three is the certain minimum and the prayer is completed accordingly.
