[Machine] The Messenger of Allah ﷺ said: "If any of you has doubts about his prayer and does not know how many units he has prayed, then he should pray one unit (rak'ah) and prostrate twice while sitting before the salutation (salam). If the prayer he has prayed is his fifth unit (rak'ah), then he should perform these two prostrations with intention of seeking forgiveness (tawbah) from Satan. This narration has been narrated from the hadith of Sulayman bin Bilal and Hisham bin Saad from Zaid bin Aslam from Ata bin Yasar from Abu Sa'id, connected in the chain of narrators. This has also been narrated from the hadith of Malik, attributed to the same chain of narrators."  

أَنَّ رَسُولَ اللهِ ﷺ قَالَ إِذَا شَكَّ أَحَدُكُمْ فِي صَلَاتِهِ فَلَمْ يَدْرِ كَمْ صَلَّى ثَلَاثًا أَوْ أَرْبَعًا فَلْيُصَلِّ رَكْعَةً وَلْيَسْجُدْ سَجْدَتَيْنِ وَهُوَ جَالِسٌ قَبْلَ التَّسْلِيمِ فَإِنْ كَانَتِ الرَّكْعَةُ الَّتِي صَلَّى خَامِسَةً شَفَعَهَا بِهَاتَيْنِ وَإِنْ كَانَتْ رَابِعَةً فَالسَّجْدَتَانِ تَرْغِيمٌ لِلشَّيْطَانِ وَقَدْ رُوِّينَاهُ مِنْ حَدِيثِ سُلَيْمَانَ بْنِ بِلَالٍ وَهِشَامِ بْنِ سَعْدٍ عَنْ زَيْدِ بْنِ أَسْلَمَ عَنْ عَطَاءِ بْنِ يَسَارٍ عَنْ أَبِي سَعِيدٍ مَوْصُولًا وَقَدْ رُوِيَ مِنْ حَدِيثِ مَالِكٍ أَيْضًا مَوْصُولًا  

[Machine] The Messenger of Allah ﷺ said, "If any of you have doubt about his prayer, he should not know whether he prayed three or four units (rak'ahs). He should dismiss the doubt and be certain. Then he should perform two prostrations before making the tasleem (saying salaam at the end of the prayer). If it is an odd number of units, he should make it an intercessory one through these two prostrations, and if it is an even number, these two prostrations become a means of rebuke for Satan."  

قَالَ رَسُولُ اللهِ ﷺ إِذَا شَكَّ أَحَدُكُمْ فِي صَلَاتِهِ فَلَا يَدْرِي أَثْلَاثًا صَلَّى أَمْ أَرْبَعًا فَلْيُلْقِ الشَّكَّ وَلْيَبْنِ عَلَى الْيَقِينِ ثُمَّ لِيَسْجُدْ سَجْدَتَيْنِ قَبْلَ أَنْ يُسَلِّمَ فَإِنْ كَانَتْ وِتْرًا أَشْفَعَهَا بِهَاتَيْنِ السَّجْدَتَيْنِ وَإِنْ كَانَتْ شَفْعًا فَالسَّجْدَتَانِ تَرْغِيمٌ لِلشَّيْطَانِ  

“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)   

سَمِعْتُ النَّبِيَّ ﷺ يَقُولُ إِذَا شَكَّ أَحَدُكُمْ فِي صَلَاتِهِ فَشَكَّ فِي الْوَاحِدَةِ وَالثِّنْتَيْنِ فَلْيَجْعَلْهَا وَاحِدَةً وَإِذَا شَكَّ فِي الِاثْنَتَيْنِ وَالثَّلَاثِ فَلْيَجْعَلْهَا اثْنَتَيْنِ وَإِذَا شَكَّ فِي الثَّلَاثِ وَالْأَرْبَعِ فَلْيَجْعَلْهَا ثَلَاثًا حَتَّى يَكُونَ الْوَهْمُ فِي الزِّيَادَةِ وَيَسْجُدْ سَجْدَتَيْنِ قَبْلَ أَنْ يُسَلِّمَ ثُمَّ يُسَلِّمُ  

[Machine] He said, the Messenger of Allah ﷺ said, "Satan comes to one of you during his prayer and confuses him until he does not know how much he has prayed. So if any of you experiences this, let him perform two prostrations while sitting."  

أَنَّهُ قَالَ قَالَ رَسُولُ اللهِ ﷺ يَأْتِي الشَّيْطَانُ أَحَدَكُمْ فِي صَلَاتِهِ فَيُلَبِّسُ عَلَيْهِ حَتَّى لَا يَدْرِي كَمْ صَلَّى فَإِذَا وَجَدَ أَحَدُكُمْ ذَلِكَ فَلْيَسْجُدْ سَجْدَتَيْنِ وَهُوَ جَالِسٌ  

[Machine] The Messenger of Allah ﷺ said: "If one of you prays and does not know if he has increased or decreased (in the prayer), then he should perform two prostrations while he is sitting, then he should offer the salutation. Abu Ali Al-Rudhbari informed us that Abu Bakr ibn Dasa narrated to us, Abu Dawood narrated to us, Hajjaj narrated to us, Ya'qub narrated to us, my father narrated to me from Ibn Ishaq, he said: Muhammad ibn Muslim Al-Zuhri informed me with his chain of transmission, and he said: "He should perform two prostrations before offering the salutation, then he should offer the salutation." And Ibn Ishaq mentioned another chain of transmission in it.  

أَنَّ رَسُولَ اللهِ ﷺ قَالَ إِذَا صَلَّى أَحَدُكُمْ فَلَمْ يَدْرِ أَزَادَ أَمْ نَقَصَ فَلْيَسْجُدْ سَجْدَتَيْنِ وَهُوَ جَالِسٌ ثُمَّ لِيُسَلِّمْ 3831 أَخْبَرَنَا أَبُو عَلِيٍّ الرُّوذْبَارِيُّ أنبأ أَبُو بَكْرِ بْنُ دَاسَةَ ثنا أَبُو دَاوُدَ ثنا حَجَّاجٌ ثنا يَعْقُوبُ ثنا أَبِي عَنِ ابْنِ إِسْحَاقَ قَالَ حَدَّثَنِي مُحَمَّدُ بْنُ مُسْلِمٍ الزُّهْرِيُّ بِإِسْنَادِهِ وَقَالَ فَلْيَسْجُدْ سَجْدَتَيْنِ قَبْلَ أَنْ يُسَلِّمَ ثُمَّ يُسَلِّمُ وَلِابْنِ إِسْحَاقَ فِيهِ إِسْنَادٌ آخَرُ  

[Machine] The Messenger of Allah ﷺ said, "When the believer calls the Adhan, the devil runs away from the mosque, breaking wind. And when the Mu'adhin becomes silent, he returns. And when the Mu'adhin stands to lead the prayer, he again goes away, having a sneeze. And when the Mu'adhin becomes silent, he returns until he comes between the Muslim and himself in prayer. He does not know if he has increased or decreased in his prayer. So when one of you finds this, let him prostrate two prostrations while sitting before he says the Salam. This was narrated by Hisham al-Dastuwai and Al-Awza'i on the authority of Yahya ibn Abi Kathir, on the authority of Abu Salamah, without this addition. And it was also narrated by Ikrimah ibn Ammar on the authority of Yahya, and he mentioned it."  

أَنَّ رَسُولَ اللهِ ﷺ قَالَ إِذَا أَذَّنَ الْمُؤْمِنُ خَرَجَ الشَّيْطَانُ مِنَ الْمَسْجِدِ لَهُ حُصَاصٌ فَإِذَا سَكَتَ الْمُؤَذِّنُ رَجَعَ فَإِذَا أَقَامَ الْمُؤَذِّنُ خَرَجَ مِنَ الْمَسْجِدِ وَلَهُ ضُرَاطٌ فَإِذَا سَكَتَ رَجَعَ حَتَّى يَأْتِيَ الْمَرْءَ الْمُسْلِمَ فِي صَلَاتِهِ فَيَدْخُلَ بَيْنَهُ وَبَيْنَ نَفْسِهِ لَا يَدْرِي أَزَادَ فِي صَلَاتِهِ أَوْ نَقَصَ فَإِذَا وَجَدَ ذَلِكَ أَحَدُكُمْ فَلْيَسْجُدْ سَجْدَتَيْنِ وَهُوَ جَالِسٌ قَبْلَ أَنْ يُسَلِّمَ ثُمَّ يُسَلِّمُ وَرَوَاهُ هِشَامٌ الدَّسْتُوَائِيُّ وَالْأَوْزَاعِيُّ عَنْ يَحْيَى بْنِ أَبِي كَثِيرٍ عَنْ أَبِي سَلَمَةَ دُونَ هَذِهِ الزِّيَادَةِ وَرَوَاهُ عِكْرِمَةُ بْنُ عَمَّارٍ عَنْ يَحْيَى فَذَكَرَهَا  

[Machine] The Messenger of Allah ﷺ said, "If one of you forgets to recite an increase or decrease while in prayer, then let him make two prostrations while sitting, then he should say the salutation." And likewise.  

قَالَ رَسُولُ اللهِ ﷺ إِذَا سَهَا أَحَدُكُمْ فَلَمْ يَدْرِ أَزَادَ أَوْ نَقَصَ فَلْيَسْجُدْ سَجْدَتَيْنِ وَهُوَ جَالِسٌ ثُمَّ يُسَلِّمُ وَكَذَلِكَ  

[Machine] The Messenger of Allah ﷺ stood up during two times of the Dhuhr or Asr prayer. When he stood straight, he did not sit back until he completed his prayer. Then he performed the two prostrations of forgetfulness before saying the taslim (ending of the prayer), and then he said the taslim.  

أَنَّ رَسُولَ اللهِ ﷺ قَامَ فِي اثْنَتَيْنِ مِنَ الظُّهْرِ أَوِ الْعَصْرِ فَلَمَّا اعْتَدَلَ قَائِمًا لَمْ يَرْجِعْ حَتَّى قَضَى صَلَاتَهُ ثُمَّ سَجَدَ سَجْدَتَيِ السَّهْوِ قَبْلَ أَنْ يُسَلِّمَ ثُمَّ يُسَلِّمُ  

[Machine] The Prophet ﷺ prayed with us, then he stood for the first two units of prayer before sitting. He continued with his prayer, and when he finished, he waited for the people to finish their salutations. Then he said the takbeer and prostrated before saying the salutation. Then he raised his head, said the takbeer, prostrated again, and raised his head and said the salutation.  

صَلَّى بِنَا رَسُولُ اللهِ ﷺ فَقَامَ فِي الرَّكْعَتَيْنِ الْأُولَيَيْنِ قَبْلَ أَنْ يَجْلِسَ فَمَضَى فِي صَلَاتِهِ فَلَمَّا قَضَى صَلَاتَهُ وَانْتَظَرَ النَّاسُ تَسْلِيمَهُ كَبَّرَ فَسَجَدَ قَبْلَ أَنْ يُسَلِّمَ ثُمَّ رَفَعَ رَأْسَهُ ثُمَّ كَبَّرَ فَسَجَدَ ثُمَّ رَفَعَ رَأْسَهُ وَسَلَّمَ  

[Machine] For Umar ibn Abdul Aziz, may Allah have mercy on him, the two prostrations (sujood) were performed before the salutation.  

لِعُمَرَ بْنِ عَبْدِ الْعَزِيزِ رَحِمَهُ اللهُ السَّجْدَتَانِ قَبْلَ السَّلَامِ
