Messenger of Allah ﷺ said, "When anyone of you stands for the prayers, Satan comes and puts him in doubts till he forgets how many rakʿat he has prayed. So if this happens to anyone of you, he should perform two prostrations of Sahu while sitting.

أَنَّ رَسُولَ اللَّهِ ﷺ قَالَ إِنَّ أَحَدَكُمْ إِذَا قَامَ يُصَلِّي جَاءَ الشَّيْطَانُ فَلَبَسَ عَلَيْهِ حَتَّى لاَ يَدْرِيَ كَمْ صَلَّى فَإِذَا وَجَدَ ذَلِكَ أَحَدُكُمْ فَلْيَسْجُدْ سَجْدَتَيْنِ وَهُوَ جَالِسٌ

The Messenger of Allah ﷺ said: When any one of you stands up to pray, the devil comes to him and confuses him to that he does not know how much he has prayed. If any one of you has such an experience he should perform two prostrations while sitting down (in qa'da).

أَنَّ رَسُولَ اللَّهِ ﷺ قَالَ إِنَّ أَحَدَكُمْ إِذَا قَامَ يُصَلِّي جَاءَهُ الشَّيْطَانُ فَلَبَسَ عَلَيْهِ حَتَّى لاَ يَدْرِي كَمْ صَلَّى فَإِذَا وَجَدَ ذَلِكَ أَحَدُكُمْ فَلْيَسْجُدْ سَجْدَتَيْنِ وَهُوَ جَالِسٌ

Abu Hurairah reported the Messenger of Allah ﷺ as saying; When one of you stands up to pray, the devil comes to him and confuses him so that he does not know how much he has prayed. If any of you has such an experience, he should perform two prostrations while he is sitting. Abu Dawud said; This tradition has been narrated in a similar manner by Ibn ‘Uyainab, Ma’mar and al-Laith.

أَنَّ رَسُولَ اللَّهِ ﷺ قَالَ إِنَّ أَحَدَكُمْ إِذَا قَامَ يُصَلِّي جَاءَهُ الشَّيْطَانُ فَلَبَسَ عَلَيْهِ حَتَّى لاَ يَدْرِي كَمْ صَلَّى فَإِذَا وَجَدَ أَحَدُكُمْ ذَلِكَ فَلْيَسْجُدْ سَجْدَتَيْنِ وَهُوَ جَالِسٌ

Messenger of Allah (S) said: "Indeed the Shaitan comes to one of you in his Salat confusing him until he does now know how much he has prayed. When one of you experiences that then let him perform two prostrations while sitting."

قَالَ رَسُولُ اللَّهِ ﷺ إِنَّ الشَّيْطَانَ يَأْتِي أَحَدَكُمْ فِي صَلاَتِهِ فَيَلْبِسُ عَلَيْهِ حَتَّى لاَ يَدْرِي كَمْ صَلَّى فَإِذَا وَجَدَ ذَلِكَ أَحَدُكُمْ فَلْيَسْجُدْ سَجْدَتَيْنِ وَهُوَ جَالِسٌ

The Messenger of Allah ﷺ said: "When any one of you gets up and prays, the Shaitan comes to him an confuses him until he does not know how many (Rak'ahs) he prayed. If any one of you notices that, let him prostrate twice when he is sitting."

أَنَّ رَسُولَ اللَّهِ ﷺ قَالَ إِنَّ أَحَدَكُمْ إِذَا قَامَ يُصَلِّي جَاءَهُ الشَّيْطَانُ فَلَبَسَ عَلَيْهِ صَلاَتَهُ حَتَّى لاَ يَدْرِي كَمْ صَلَّى فَإِذَا وَجَدَ أَحَدُكُمْ ذَلِكَ فَلْيَسْجُدْ سَجْدَتَيْنِ وَهُوَ جَالِسٌ

“I heard the Messenger of Allah ﷺ say: ‘If anyone of you is uncertain as to whether he has prayed one or two Rak’ah, let him assume it is one. If he is uncertain as to whether he has prayed two or three, let him assume it is two. If he is uncertain as to whether he has prayed three or four, let him assume it is three. Then let him complete what is left of his prayer, so that the doubt will be about what is more. Then let him prostrate twice while he is sitting, before the Taslim (saying the Salam).’”

سَمِعْتُ رَسُولَ اللَّهِ ﷺ يَقُولُ إِذَا شَكَّ أَحَدُكُمْ فِي الثِّنْتَيْنِ وَالْوَاحِدَةِ فَلْيَجْعَلْهَا وَاحِدَةً وَإِذَا شَكَّ فِي الثِّنْتَيْنِ وَالثَّلاَثِ فَلْيَجْعَلْهَا ثِنْتَيْنِ وَإِذَا شَكَّ فِي الثَّلاَثِ وَالأَرْبَعِ فَلْيَجْعَلْهَا ثَلاَثًا ثُمَّ لْيُتِمَّ مَا بَقِيَ مِنْ صَلاَتِهِ حَتَّى يَكُونَ الْوَهْمُ فِي الزِّيَادَةِ ثُمَّ يَسْجُدْ سَجْدَتَيْنِ وَهُوَ جَالِسٌ قَبْلَ أَنْ يُسَلِّمَ

“The Satan comes to any one of you while he is praying and comes between him and his soul, until he does not know whether he as added something or omitted something. If that happens, then he should prostrate twice before the Salam, then he should say the Salam.”

أَنَّ النَّبِيَّ ﷺ قَالَ إِنَّ الشَّيْطَانَ يَأْتِي أَحَدَكُمْ فِي صَلاَتِهِ فَيَدْخُلُ بَيْنَهُ وَبَيْنَ نَفْسِهِ حَتَّى لاَ يَدْرِي زَادَ أَوْ نَقَصَ فَإِذَا كَانَ ذَلِكَ فَلْيَسْجُدْ سَجْدَتَيْنِ قَبْلَ أَنْ يُسَلِّمَ ثُمَّ يُسَلِّمْ

“The Satan comes between the son of Adam and his soul, and he does not know how many Rak’ah he has prayed. If a person notices that, then let him prostrate twice before he says the Salam.”

أَنَّ النَّبِيَّ ﷺ قَالَ إِنَّ الشَّيْطَانَ يَدْخُلُ بَيْنَ ابْنِ آدَمَ وَبَيْنَ نَفْسِهِ فَلاَ يَدْرِي كَمْ صَلَّى فَإِذَا وَجَدَ ذَلِكَ فَلْيَسْجُدْ سَجْدَتَيْنِ قَبْلَ أَنْ يُسَلِّمَ

[AI] I heard from the Messenger of Allah or one of his companions, "When a man is uncertain about his prayer, what should he do?" He said, "While in this state, Abdullah ibn Awf approached and asked, 'Who are you two?'" Umar said, "I asked this young man if he had heard from the Messenger of Allah or any of his companions, what should one do when uncertain about their prayer?" Abdullah ibn Awf said, "I heard the Messenger of Allah say, 'If one of you is uncertain about their prayer and does not know whether they have prayed one or two (units), then let them make it one. And if they do not know whether they have prayed two or three, then let them make it two. And if they do not know whether they have prayed three or four, then let them make it three. Then let them prostrate when they finish their prayer while seated before they give the salutations with two prostrations.'"

سَمِعْتَ مِنْ رَسُولِ اللهِ ﷺ أَوْ مِنْ أَحَدٍ مِنْ أَصْحَابِهِ إِذَا شَكَّ الرَّجُلُ فِي صَلاتِهِ مَاذَا يَصْنَعُ؟ قَالَ فَبَيْنَا هُوَ كَذَلِكَ إِذِ اقْبَلَ عَبْدُ الرَّحْمَنِ بْنُ عَوْفٍ فَقَالَ فِيمَ أَنْتُمَا؟فَقَالَ عُمَرُ سَأَلْتُ هَذَا الْغُلامَ هَلْ سَمِعَ مِنْ رَسُولِ اللهِ ﷺ أَوْ أَحَدٍ مِنْ أَصْحَابِهِ إِذَا شَكَّ الرَّجُلُ فِي صَلاتِهِ مَاذَا يَصْنَعُ؟ فَقَالَ عَبْدُ الرَّحْمَنِ سَمِعْتُ رَسُولَ اللهِ ﷺ يَقُولُ إِذَا شَكَّ أَحَدُكُمْ فِي صَلاتِهِ فَلَمْ يَدْرِ أَوَاحِدَةً صَلَّى أَمْ ثِنْتَيْنِ؟ فَلْيَجْعَلْهَا وَاحِدَةً وَإِذَا لَمْ يَدْرِ ثِنْتَيْنِ صَلَّى أَمْ ثَلاثًا؟ فَلْيَجْعَلْهَا ثِنْتَيْنِ وَإِذَا لَمْ يَدْرِ أَثَلاثًا صَلَّى أَمِ ارْبَعًا؟ فَلْيَجْعَلْهَا ثَلاثًا ثُمَّ يَسْجُدِ اذَا فَرَغَ مِنْ صَلاتِهِ وَهُوَ جَالِسٌ قَبْلَ أَنْ يُسَلِّمَ سَجْدَتَيْنِ

[AI] "If one of you prays and doubts in his prayer, then if he doubts between one and two, let him make them one. If he doubts between two and three, let him make them two. If he doubts between three and four, let him make them three, until the doubt is in the addition. Then let him prostrate two prostrations before he gives salam, then let him give salam." I sat with Umar ibn al-Khattab, and he said: "O Ibn Abbas, if a man becomes uncertain in his prayer and does not know whether he added or omitted?" I said: "By Allah, O Commander of the Faithful, I do not know; I have not heard anything about that." Umar said: "By Allah, I do not know." He said: "While we were in that state, Abd al-Rahman ibn Awf came." He said: "What is this that you two are discussing?" Umar said to him: "We mentioned the man who doubts in his prayer, how he should act." He said: "I heard the Messenger of Allah ﷺ say this hadith."

«إِذَا صَلَّى أَحَدُكُمْ فَشَكَّ فِي صَلاتِهِ، فَإِنْ شَكَّ فِي الْوَاحِدَةِ وَالثِّنْتَيْنِ، فَلْيَجْعَلْهُمَا وَاحِدَةً، وَإِنْ شَكَّ فِي الثِّنْتَيْنِ وَالثَّلاثِ، فَلْيَجْعَلْهُمَا ثِنْتَيْنِ، وَإِنْ شَكَّ فِي الثَّلاثِ وَالْأَرْبَعِ، فَلْيَجْعَلْهُمَا ثَلاثًا، حَتَّى يَكُونَ الْوَهْمُ فِي الزِّيَادَةِ، ثُمَّ يَسْجُدْ سَجْدَتَيْنِ قَبْلَ أَنْ يُسَلِّمَ، ثُمَّ يُسَلِّمْ». جَلَسْتُ إِلَى عُمَرَ بْنِ الْخَطَّابِ، فَقَالَ: يَا ابْنَ عَبَّاسٍ، إِذَا اشْتَبَهَ عَلَى الرَّجُلِ فِي صَلاتِهِ، فَلَمْ يَدْرِ أَزَادَ أَمْ نَقَصَ؟ قُلْتُ: وَاللهِ يَا أَمِيرَ الْمُؤْمِنِينَ، مَا أَدْرِي مَا سَمِعْتُ فِي ذَلِكَ شَيْئًا. فَقَالَ عُمَرُ: وَاللهِ مَا أَدْرِي. قَالَ: فَبَيْنَا نَحْنُ عَلَى ذَلِكَ، إِذْ جَاءَ عَبْدُ الرَّحْمَنِ بْنُ عَوْفٍ، فَقَالَ: مَا هَذَا الَّذِي تَذَاكَرَانِ؟ فَقَالَ لَهُ عُمَرُ: ذَكَرْنَا الرَّجُلَ يَشُكُّ فِي صَلاتِهِ، كَيْفَ يَصْنَعُ. فَقَالَ: سَمِعْتُ رَسُولَ اللهِ ﷺ يَقُولُ هَذَا الْحَدِيثَ.

[AI] The Prophet ﷺ said, "When one of you is in prayer, the devil comes to him and distracts him so that he does not know how much he has prayed. So, whoever experiences this, let him perform two prostrations while sitting."

النَّبِيَّ ﷺ يَأْتِي أَحَدَكُمُ الشَّيْطَانُ وَهُوَ فِي صَلَاتِهِ فَيَلْبِسُ عَلَيْهِ حَتَّى لَا يَدْرِيَ كَمْ صَلَّى فَمَنْ وَجَدَ مِنْ ذَلِكَ شَيْئًا فَلْيَسْجُدْ سَجْدَتَيْنِ وَهُوَ جَالِسٌ

Messenger of Allah (S) said: "Indeed the Shaitan comes to one of you in his Salat confusing him until he does now know how much he has prayed. When one of you experiences that then let him perform two prostrations while sitting." (Using translation from Tirmidhī 397)

أَنَّهُ قَالَ قَالَ رَسُولُ اللهِ ﷺ يَأْتِي أَحَدَكُمُ الشَّيْطَانُ وَهُوَ فِي صَلَاتِهِ فَيَلْبِسُ عَلَيْهِ حَتَّى لَا يَدْرِيَ كَمْ صَلَّى فَإِذَا وَجَدَ ذَلِكَ فَلْيَسْجُدْ سَجْدَتَيْنِ وَهُوَ جَالِسٌ

[AI] From the Prophet, ﷺ , he said: Indeed, Satan comes to one of you during his prayer, and he does not know whether he has increased or decreased [his prayer]. So, when one of you finds that, let him perform two prostrations.

عَنِ النَّبِيِّ ﷺ قَالَ إِنَّ الشَّيْطَانَ يَأْتِي أَحَدَكُمْ فِي صَلَاتِهِ فَلَا يَدْرِي أَزَادَ أَمْ نَقَصَ فَإِذَا وَجَدَ أَحَدُكُمْ ذَلِكَ فَلْيَسْجُدْ سَجْدَتَيْنِ

Messenger of Allah (S) said: "Indeed the Shaitan comes to one of you in his Salat confusing him until he does now know how much he has prayed. When one of you experiences that then let him perform two prostrations while sitting." (Using translation from Tirmidhī 397)

قَالَ رَسُولُ اللهِ ﷺ يَأْتِي أَحَدَكُمُ الشَّيْطَانُ فَيَلْبِسُ عَلَيْهِ فِي صَلَاتِهِ فَلَا يَدْرِي أَزَادَ أَمْ نَقَصَ فَإِذَا وَجَدَ أَحَدُكُمْ ذَلِكَ فَلْيَسْجُدْ سَجْدَتَيْنِ وَهُوَ جَالِسٌ

Yahya related to me from Malik from Ibn Shihab from Abu Salama ibn Abdar-Rahman ibn Awf from Abu Hurayra that the Messenger of Allah ﷺ said, "When you stand in prayer, Shaytan comes to you and confuses you until you do not know how much you have prayed. If you find that happening do two sajdas from the sitting position."

أَنَّ رَسُولَ اللَّهِ ﷺ قَالَ إِنَّ أَحَدَكُمْ إِذَا قَامَ يُصَلِّي جَاءَهُ الشَّيْطَانُ فَلَبَسَ عَلَيْهِ حَتَّى لاَ يَدْرِي كَمْ صَلَّى فَإِذَا وَجَدَ ذَلِكَ أَحَدُكُمْ فَلْيَسْجُدْ سَجْدَتَيْنِ وَهُوَ جَالِسٌ

[AI] I heard from the Messenger of Allah ﷺ or from one of his companions what he mentioned that the Messenger of Allah ﷺ commanded when a person makes a mistake in their prayer. I asked: "Have you heard anything about this, O Amir al-Mumineen?" He replied: "No." Then Abdullah ibn Awf entered upon us and asked: "What are you discussing?" Umar said: "I asked him if he heard the Messenger of Allah ﷺ or any of his companions mention what the Messenger of Allah ﷺ commanded when a person makes a mistake in their prayer." Abdullah ibn Awf said: "I have knowledge of that." Umar said: "Come forth and narrate, for you are the just and trustworthy." Abdullah ibn Awf said: "I heard the Messenger of Allah ﷺ say, 'If one of you is uncertain between two scenarios [in prayer], then they should choose the one that is less in number. And if one is uncertain between two scenarios and a third, they should choose the two. And if one is uncertain between three scenarios and four, they should choose the three. Then they should complete what remains of their prayer until the doubt only pertains to the extra [acts of worship]. Then they should prostrate twice while sitting before completing their prayer.'"

سَمِعْتَ مِنْ رَسُولِ اللَّهِ ﷺ أَوْ مِنْ أَحَدٍ مِنْ أَصْحَابِهِ مَا يَذْكُرُ مَا أَمَرَ بِهِ رَسُولُ اللَّهِ ﷺ إِذَا سَهَا الْمَرْءُ فِي صَلَاتِهِ؟ قُلْتُ لَا أَوَمَا سَمِعْتَ يَا أَمِيرَ الْمُؤْمِنِينَ؟ قَالَ لَا فَدَخَلَ عَلَيْنَا عَبْدُ الرَّحْمَنِ بْنُ عَوْفٍ فَقَالَ فِيمَا أَنْتُمَا؟ فَقَالَ عُمَرُ سَأَلْتُهُ هَلْ سَمِعَ رَسُولَ اللَّهِ ﷺ أَوْ مِنْ أَحَدٍ مِنْ أَصْحَابِهِ يَذْكُرُ مَا أَمَرَ بِهِ رَسُولُ اللَّهِ ﷺ إِذَا سَهَا الْمَرْءُ فِي صَلَاتِهِ فَقَالَ عَبْدُ الرَّحْمَنِ عِنْدِي عِلْمٌ مِنْ ذَلِكَ فَقَالَ عُمَرُ هَلُمَّ فَأَنْتَ الْعَدْلُ الرِّضَا فَقَالَ عَبْدُ الرَّحْمَنِ سَمِعْتُ رَسُولَ اللَّهِ ﷺ يَقُولُ «إِذَا شَكَّ أَحَدُكُمْ فِي الِاثْنَتَيْنِ فَلْيَجْعَلْهُمَا وَاحِدَةً وَإِذَا شَكَّ فِي الِاثْنَتَيْنِ وَالثَّلَاثِ فَلْيَجْعَلْهُمَا اثْنَتَيْنِ وَإِذَا شَكَّ فِي الثَّلَاثِ وَالْأَرْبَعِ فَلْيَجْعَلْهُمَا ثَلَاثًا ثُمَّ يُتِمُّ مَا بَقِيَ مِنْ صَلَاتِهِ حَتَّى يَكُونَ الْوَهْمُ فِي الزِّيَادَةِ ثُمَّ يَسْجُدُ سَجْدَتَيْنِ وَهُوَ جَالِسٌ قَبْلَ أَنْ يُسَلِّمَ»

[AI] I sat with Umar bin Al-Khattab, and he said: "O Ibn Abbas, have you heard from the Prophet ﷺ about a person who forgets their prayer and does not know whether they increased or decreased in it?" I said: "And have you heard anything about it, O Amir al-Mu'minin, from the Messenger of Allah ﷺ ?" He said: "No, by Allah, I have not heard anything from him regarding it, nor have I asked him about it. But when Abdur-Rahman bin Awf came, Umar informed him about it. And Abdur-Rahman said: 'But I have heard this from the Prophet ﷺ .' Umar said: 'Then you have the knowledge that we were seeking, so what did you hear?' Abdur-Rahman said: 'I heard the Prophet ﷺ say: If any one of you is in doubt about his prayer, then he should consider it as one unit (rak'ah) and two units (rak'ah), and if he is in doubt about two units (rak'ah) or three, then he should consider it as two units (rak'ah), and if he is in doubt about three or four, then he should consider it as three units (rak'ah), until the doubt concerning the addition is removed, and he should prostrate twice before he gives the Salam, then he should give the Salam, and this is its meaning.'"

“I heard the Messenger of Allah ﷺ say: ‘If anyone of you is uncertain as to whether he has prayed one or two Rak’ah, let him assume it is one. If he is uncertain as to whether he has prayed two or three, let him assume it is two. If he is uncertain as to whether he has prayed three or four, let him assume it is three. Then let him complete what is left of his prayer, so that the doubt will be about what is more. Then let him prostrate twice while he is sitting, before the Taslim (saying the Salam).’” (Using translation from Ibn Mājah 1209)

"إذَا شكَّ أَحدُكمْ في الاثْنتينِ أو الواحِدَةِ فَليجعلْها واحدةً وإذا شَكَّ في الثنْتَين والثَّلاثِ فليَجْعَلها اثنتين، وإذا شَكَّ في الثلاث والأرْبَعِ فليجعلها ثلاثًا، حتَّى يكونَ الوهْمُ في الزيادة، ثم لْيُتِمَّ ما بَقِي من صلاته، ثم يسْجُد سجدتين وهو جالسٌ قْبلَ أنْ يسلِّمَ ".

Messenger of Allah ﷺ said, "When anyone of you stands for the prayers, Satan comes and puts him in doubts till he forgets how many rakʿat he has prayed. So if this happens to anyone of you, he should perform two prostrations of Sahu while sitting. (Using translation from Bukhārī 1232)

"إِنَّ الشَّيطَانَ يَأْتِي أَحَدَكُمْ في صَلاته فَيُلْبِسُ عليه حَتَّى لا يَدْرى كَمْ صَلَّى. فَإِذَا وَجَدَ ذَلكَ أَحَدُكُمْ فَليَسْجُدْ سَجْدَتَينِ وَهُوَ جَالِسٌ قَبْلَ أن يُسَلَّمَ، ثُمَّ يُسَلِّمْ".

"إِنَّ أحَدَكُمْ إِذا قام يُصَلِّى جاءَ الشيطان فَلَبَّسَ عليه حتى لا يدرى: كَمْ صَلَّى؟ فَإِذَا وَجَد ذلِك أحدُكم فَليَسْجُد سَجْدَتَيْن وهو جَالِسٌ".
