Performing the Prostration of Forgetfulness for Errors in Prayer
The hadith
إِذَا شَكَّ أَحَدُكُمْ فِي صَلَاتِهِ فَلَمْ يَدْرِ كَمْ صَلَّى، ثَلَاثًا أَمْ أَرْبَعًا، فَلْيَطْرَحِ الشَّكَّ وَلْيَبْنِ عَلَى مَا اسْتَيْقَنَ، ثُمَّ يَسْجُدُ سَجْدَتَيْنِ قَبْلَ أَنْ يُسَلِّمَ
The Prophet ﷺ said: 'When one of you doubts during his prayer and does not know whether he prayed three or four [rakʿahs], let him put away the doubt and build on what he is certain of. Then let him perform two prostrations (sajdatayn) before the salām.' (Ṣaḥīḥ Muslim 571, narrated by Abū Saʿīd al-Khudrī ra.) Cross-ref Bukhārī 401-404 on the various forms of sujūd as-sahw. Performed whenever an error occurs.
Svenska: Profeten ﷺ sade: 'När någon av er tvekar i sin bön och inte vet om han bett tre eller fyra rakat, låt honom kasta bort tvivlet och bygga på det han är säker på. Sedan ska han utföra två sajdor före salam.'
The story
The Prophet ﷺ once prayed Ẓuhr with five rakʿahs by accident (Bukhārī 401). When he was told, he performed two prostrations after the salām and said: 'I am only a human being; I forget as you forget. So if I forget, remind me.' (Bukhārī 401.) The hadith is striking: the Prophet ﷺ explicitly named his own humanity and the prophetic correction. The Companions used the same correction; the Sunnah established the practice.
Why it's here
The Prophet ﷺ established the prostration of forgetfulness as the structural correction for errors in prayer: forgetting a rakʿah, adding one, doubting the count, missing the first tashahhud, missing other elements. The two extra prostrations correct the prayer without invalidating it. The Sunnah teaches that imperfection in prayer is expected and that the religion provides a structural correction. The believer is therefore freed from the anxiety of needing to repeat the entire prayer for a small error.
Try it today
1. Learn the four cases that require sujūd as-sahw: (1) adding to the prayer, (2) leaving out a wājib, (3) doubt in count, (4) missing the first tashahhud or similar. 2. The two prostrations are performed before the salām (per most cases) or after (per other cases, depending on the madhhab). 3. Recite the standard sajdah dhikr in each prostration: 'subḥāna rabbiya al-aʿlā.' 4. Make salām after the two prostrations.
In your day
Most modern Muslims either do not know sujūd as-sahw or skip it when an error occurs. Learn it. Practice it the next time you make an error. The Sunnah's structural correction is part of the religion's mercy: imperfection is expected; the correction is provided.
A reflection to carry
Sujūd as-sahw: the prostration of forgetfulness. When the believer doubts the rakʿah-count, forgets a wajib, or adds extra, the structural correction is two prostrations. The Prophet ﷺ established the protocol.
Read the longer reflection
The Prophet ﷺ: when uncertain, choose the lesser count and do two sujūd at the end of prayer (Bukhārī 401). The structural mechanism: prayer-imperfections are corrected by additional prayer-acts, not by abandoning or restarting. Cure: learn the sujūd as-sahw protocol; when in doubt during ṣalāh, do not panic; complete the prayer; perform the two prostrations at the end before taslīm (or after, depending on the case). The classical scholars treated this as the Prophet's ﷺ specific gift to the umma: a structural correction-mechanism that preserves ṣalāh-completeness despite human imperfection.
