“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  

[Machine] 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  

[Machine] The Messenger of Allah ﷺ said: "If one of you has doubts about his prayer, then if he doubts between one and two, let him take them as one. And if he doubts between two and three, let him take them as two. And if he doubts between three and four, let him take them as three, until the uncertainty lies in the extra (rak'ah). Then he should make two prostrations before he says the Salam." Muhammad ibn Ishaq said: "Husayn ibn Abdullah asked me, 'Did he narrate this to you?' I said, 'No.' He said, 'But he informed me that Kurayb, the freed slave of Ibn Abbas, narrated to him from Ibn Abbas, who said, 'I sat with Umar ibn al-Khattab and he said, 'O Ibn Abbas, if a person is confused in his prayer and does not know whether he has added or missed something, what should he do?' I said, 'By Allah, O Amir al-Mu'minin (Commander of the Faithful), I do not know anything about that.' Umar said, 'By Allah, I do not know either.' While we were discussing this, Abd al-Rahman ibn Awf came and said, 'What are you two talking about?' Umar said, 'We were discussing a man who has doubts about his prayer and what he should do.' Abd al-Rahman said, 'I heard the Messenger of Allah ﷺ say this.'"  

أَنَّ رَسُولَ اللهِ ﷺ قَالَ 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 قَالَ مُحَمَّدُ بْنُ إِسْحَاقَ وَقَالَ لِي حُسَيْنُ بْنُ عَبْدِ اللهِ هَلِ أسْنَدَهُ لَكَ؟ فَقُلْتُ لَا فَقَالَ لَكِنَّهُ حَدَّثَنِي أَنَّ كُرَيْبًا مَوْلَى ابْنِ عَبَّاسٍ حَدَّثَهُ عَنِابْنِ عَبَّاسٍ قَالَ 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  

[Machine] 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»

"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 ".  

"إِذا شَكَّ أحدُكُمْ في صَلاتِه فلم يَدْر زادَ أوْ نَقَص؟ فإِنْ كانَ شكّ في الواحدةِ وَالثِّنتين فليجْعلها واحدةً حتَّى يكونَ الوهْمُ في الزِّيادةِ ثمَّ يَسْجُدْ سجدتينِ وهو جالسٌ قَبْل أنْ يُسَلِّمَ ثُمَّ يُسَلِّمْ ".
