The Prophet ﷺ prayed (and the sub-narrator Ibrahim said, "I do not know whether he prayed more or less than usual"), and when he had finished the prayers he was asked, "O Messenger of Allah ﷺ! Has there been any change in the prayers?" He said, "What is it?' The people said, "You have prayed so much and so much." So the Prophet ﷺ bent his legs, faced the Qibla and performed two prostration's (of Sahu) and finished his prayers with Taslim (by turning his face to right and left saying: 'As-Salamu ʿAlaikum- Warahmat-ullah'). When he turned his face to us he said, "If there had been anything changed in the prayer, surely I would have informed you but I am a human being like you and liable to forget like you. So if I forget remind me and if anyone of you is doubtful about his prayer, he should follow what he thinks to be correct and complete his prayer accordingly and finish it and do two prostrations (of Sahu).  

عَبْدُ اللَّهِ صَلَّى النَّبِيُّ ﷺ قَالَ إِبْرَاهِيمُ لاَ أَدْرِي زَادَ أَوْ نَقَصَ فَلَمَّا سَلَّمَ قِيلَ لَهُ يَا رَسُولَ اللَّهِ أَحَدَثَ فِي الصَّلاَةِ شَىْءٌ قَالَ وَمَا ذَاكَ قَالُوا صَلَّيْتَ كَذَا وَكَذَا فَثَنَى رِجْلَيْهِ وَاسْتَقْبَلَ الْقِبْلَةَ وَسَجَدَ سَجْدَتَيْنِ ثُمَّ سَلَّمَ فَلَمَّا أَقْبَلَ عَلَيْنَا بِوَجْهِهِ قَالَ إِنَّهُ لَوْ حَدَثَ فِي الصَّلاَةِ شَىْءٌ لَنَبَّأْتُكُمْ بِهِ وَلَكِنْ إِنَّمَا أَنَا بَشَرٌ مِثْلُكُمْ أَنْسَى كَمَا تَنْسَوْنَ فَإِذَا نَسِيتُ فَذَكِّرُونِي وَإِذَا شَكَّ أَحَدُكُمْ فِي صَلاَتِهِ فَلْيَتَحَرَّى الصَّوَابَ فَلْيُتِمَّ عَلَيْهِ ثُمَّ يُسَلِّمْ ثُمَّ يَسْجُدْ سَجْدَتَيْنِ  

The Messenger of Allah ﷺ said the prayer; (the narrator added): He made some act of omission or commission when he pronounced salutation; it was said to him: Messenger of Allah, is there something new about the prayer? He (the Holy Prophet) said: What is it? They said: You said prayer in such and such away. He (the narrator) said: He (the Holy Prophet) turned his feet and faced the Qibla and performed two prostrations and then pronounced salutations, and then turned his face towards us and said: If there is anything new about prayer (new command from the Lord) I informed you of that. But I am a human being and I forget as you for. get, so when I forget, remind me, and when any one of you is in doubt about his prayer. he should aim at what Is correct. and complete his prayer in that respect and then make two prostrations.  

عَبْدُ اللَّهِ صَلَّى رَسُولُ اللَّهِ ﷺ قَالَ إِبْرَاهِيمُ زَادَ أَوْ نَقَصَ فَلَمَّا سَلَّمَ قِيلَ لَهُ يَا رَسُولَ اللَّهِ أَحَدَثَ فِي الصَّلاَةِ شَىْءٌ قَالَ وَمَا ذَاكَ قَالُوا صَلَّيْتَ كَذَا وَكَذَا قَالَ فَثَنَى رِجْلَيْهِ وَاسْتَقْبَلَ الْقِبْلَةَ فَسَجَدَ سَجْدَتَيْنِ ثُمَّ سَلَّمَ ثُمَّ أَقْبَلَ عَلَيْنَا بِوَجْهِهِ فَقَالَ إِنَّهُ لَوْ حَدَثَ فِي الصَّلاَةِ شَىْءٌ أَنْبَأْتُكُمْ بِهِ وَلَكِنْ إِنَّمَا أَنَا بَشَرٌ أَنْسَى كَمَا تَنْسَوْنَ فَإِذَا نَسِيتُ فَذَكِّرُونِي وَإِذَا شَكَّ أَحَدُكُمْ فِي صَلاَتِهِ فَلْيَتَحَرَّ الصَّوَابَ فَلْيُتِمَّ عَلَيْهِ ثُمَّ لْيَسْجُدْ سَجْدَتَيْنِ  

"The Messenger of Allah ﷺ prayed and did more or less (rak'ahs). When he had said the salam we said: 'O Messenger of Allah ﷺ, has there been some change concerning the prayer?' He said: 'Why are you asking?' So we told him what he had done. He turned back toward the Qiblah and prostrated two prostrations of forgetfulness, then he turned to face us and said: 'If there had been some change concerning the prayer I would have told you.' Then he said: 'Rather I am a human being and I forget as you forget. If any one of you is not sure about his prayer, let him estimate what he thinks is correct, and complete his prayer on that basis, then say the taslim and prostrate two prostrations of forgetfulness.'"  

صَلَّى رَسُولُ اللَّهِ ﷺ صَلاَةً فَزَادَ فِيهَا أَوْ نَقَصَ فَلَمَّا سَلَّمَ قُلْنَا يَا نَبِيَّ اللَّهِ هَلْ حَدَثَ فِي الصَّلاَةِ شَىْءٌ قَالَ وَمَا ذَاكَ فَذَكَرْنَا لَهُ الَّذِي فَعَلَ فَثَنَى رِجْلَهُ فَاسْتَقْبَلَ الْقِبْلَةَ فَسَجَدَ سَجْدَتَىِ السَّهْوِ ثُمَّ أَقْبَلَ عَلَيْنَا بِوَجْهِهِ فَقَالَ لَوْ حَدَثَ فِي الصَّلاَةِ شَىْءٌ لأَنْبَأْتُكُمْ بِهِ ثُمَّ قَالَ إِنَّمَا أَنَا بَشَرٌ أَنْسَى كَمَا تَنْسَوْنَ فَأَيُّكُمْ شَكَّ فِي صَلاَتِهِ شَيْئًا فَلْيَتَحَرَّ الَّذِي يَرَى أَنَّهُ صَوَابٌ ثُمَّ يُسَلِّمْ ثُمَّ يَسْجُدْ سَجْدَتَىِ السَّهْوِ  

The Messenger of Allah ﷺ prayed Zuhr then he turned to face them and they said: 'Has there been some change concerning the prayer?' He said: 'Why are you asking?' They told him what he had done, so he turned back toward the Qiblah and prostrated twice. Then he said the salam and turned to face them and said: 'I am only human, I forget as you forget, so if I forget, then remind me.' And he said: 'If there had been some change concerning the prayer I would have told you.' And he said: 'If one of you is not sure about his prayer, let him estimate what is closest to what is correct, then let him complete it on that basis, then prostrate twice.'  

كَتَبَ إِلَىَّ مَنْصُورٌ وَقَرَأْتُهُ عَلَيْهِ وَسَمِعْتُهُ يُحَدِّثُ رَجُلاً عَنْ إِبْرَاهِيمَ عَنْ عَلْقَمَةَ عَنْ عَبْدِ اللَّهِ أَنَّ رَسُولَ اللَّهِ ﷺ صَلَّى صَلاَةَ الظُّهْرِ ثُمَّ أَقْبَلَ عَلَيْهِمْ بِوَجْهِهِ فَقَالُوا أَحَدَثَ فِي الصَّلاَةِ حَدَثٌ قَالَ وَمَا ذَاكَ فَأَخْبَرُوهُ بِصَنِيعِهِ فَثَنَى رِجْلَهُ وَاسْتَقْبَلَ الْقِبْلَةَ فَسَجَدَ سَجْدَتَيْنِ ثُمَّ سَلَّمَ ثُمَّ أَقْبَلَ عَلَيْهِمْ بِوَجْهِهِ فَقَالَ إِنَّمَا أَنَا بَشَرٌ أَنْسَى كَمَا تَنْسَوْنَ فَإِذَا نَسِيتُ فَذَكِّرُونِي وَقَالَ لَوْ كَانَ حَدَثَ فِي الصَّلاَةِ حَدَثٌ أَنْبَأْتُكُمْ بِهِ وَقَالَ إِذَا أَوْهَمَ أَحَدُكُمْ فِي صَلاَتِهِ فَلْيَتَحَرَّ أَقْرَبَ ذَلِكَ مِنَ الصَّوَابِ ثُمَّ لْيُتِمَّ عَلَيْهِ ثُمَّ يَسْجُدْ سَجْدَتَيْنِ  

The Messenger of Allah ﷺ offered prayer. The version of the narrator Ibrahim goes: I do not know whether he increased or decreased (the rak'ahs of prayer). When he gave the salutation, he was asked: Has something new happened in the prayer, Messenger of Allah? He said: What is it? They said: You prayed so many and so many (rak'ahs). He then relented his foot and faced the Qiblah and made two prostrations. He then gave the salutation. When he turned away (finished the prayer), he turned his face to us and said: Had anything new happened in prayer, I would have informed you. I am only a human being and I forget just as you do; so when I forget, remind me, and when any of you is in doubt about his prayer he should aim at what is correct, and complete his prayer in that respect, then give the salutation and afterwards made two prostrations.  

عَبْدُ اللَّهِ صَلَّى رَسُولُ اللَّهِ ﷺ قَالَ إِبْرَاهِيمُ فَلاَ أَدْرِي زَادَ أَمْ نَقَصَ فَلَمَّا سَلَّمَ قِيلَ لَهُ يَا رَسُولَ اللَّهِ أَحَدَثَ فِي الصَّلاَةِ شَىْءٌ قَالَ وَمَا ذَاكَ قَالُوا صَلَّيْتَ كَذَا وَكَذَا فَثَنَى رِجْلَهُ وَاسْتَقْبَلَ الْقِبْلَةَ فَسَجَدَ بِهِمْ سَجْدَتَيْنِ ثُمَّ سَلَّمَ فَلَمَّا انْفَتَلَ أَقْبَلَ عَلَيْنَا بِوَجْهِهِ ﷺ فَقَالَ إِنَّهُ لَوْ حَدَثَ فِي الصَّلاَةِ شَىْءٌ أَنْبَأْتُكُمْ بِهِ وَلَكِنْ إِنَّمَا أَنَا بَشَرٌ أَنْسَى كَمَا تَنْسَوْنَ فَإِذَا نَسِيتُ فَذَكِّرُونِي وَقَالَ إِذَا شَكَّ أَحَدُكُمْ فِي صَلاَتِهِ فَلْيَتَحَرَّ الصَّوَابَ فَلْيُتِمَّ عَلَيْهِ ثُمَّ لْيُسَلِّمْ ثُمَّ لْيَسْجُدْ سَجْدَتَيْنِ  

“The Messenger of Allah ﷺ offered prayer, and I am not sure whether he did something extra or omitted something. He asked, and we told him, so he turned to face the Qiblah and prostrated twice, then he said the Salam. Then he turned to face us and said: ‘If any new command has been revealed concerning the prayer, I would certainly have told you. But I am only human and I forget and you forget. If I forget, then remind me. And if anyone of you is uncertain about the prayer, let him do what is closest to what is correct, then complete the prayer, say the Salam and prostrate twice.”  

صَلَّى رَسُولُ اللَّهِ ﷺ صَلاَةً لاَ يَدْرِي أَزَادَ أَوْ نَقَصَ فَسَأَلَ فَحَدَّثْنَاهُ فَثَنَى رِجْلَهُ وَاسْتَقْبَلَ الْقِبْلَةَ وَسَجَدَ سَجْدَتَيْنِ ثُمَّ سَلَّمَ ثُمَّ أَقْبَلَ عَلَيْنَا بِوَجْهِهِ فَقَالَ لَوْ حَدَثَ فِي الصَّلاَةِ شَىْءٌ لأَنْبَأْتُكُمُوهُ وَإِنَّمَا أَنَا بَشَرٌ أَنْسَى كَمَا تَنْسَوْنَ فَإِذَا نَسِيتُ فَذَكِّرُونِي وَأَيُّكُمْ مَا شَكَّ فِي الصَّلاَةِ فَلْيَتَحَرَّ أَقْرَبَ ذَلِكَ مِنَ الصَّوَابِ فَيُتِمَّ عَلَيْهِ وَيُسَلِّمَ وَيَسْجُدَ سَجْدَتَيْنِ

صَلَّى رَسُولُ اللهِ ﷺ صَلَاةً لَا أَدْرِي زَادَ أَمْ نَقَصَ إِبْرَاهِيمُ الْقَائِلُ لَا يَدْرِي عَلْقَمَةُ قَالَ زَادَ أَوْ نَقَصَ أَوْ عَبْدُ اللهِ ثُمَّ اسْتَقْبَلَنَا فَحَدَّثْنَاهُ بِصَنِيعِهِ فَثَنَى رِجْلَهُ وَاسْتَقْبَلَ الْقِبْلَةَ وَسَجَدَ سَجْدَتَيْنِ ثُمَّ أَقْبَلَ عَلَيْنَا بِوَجْهِهِ فَقَالَ لَوْ حَدَثَ فِي الصَّلَاةِ شَيْءٌ لَأَنْبَأْتُكُمُوهُ وَلَكِنْ إِنَّمَا أَنَا بَشَرٌ أَنْسَى كَمَا تَنْسَوْنَ فَإِنْ نَسِيتُ فَذَكِّرُونِي وَأَيُّكُمْ مَا شَكَّ فِي صَلَاتِهِ فَلْيَتَحَرَّ أَقْرَبَ ذَلِكَ لِلصَّوَابِ فَلْيُتِمَّ عَلَيْهِ وَيُسَلِّمْ ثُمَّ يَسْجُدْ سَجْدَتَيْنِ  

[Machine] The messenger of Allah ﷺ prayed with us a prayer in which he either added or omitted something. When he finished, we asked, "O messenger of Allah, did you introduce something new in the prayer?" He replied, "I did not introduce anything new in the prayer. However, I am a human being and I forget just as you forget. So if I forget, remind me, and if any one of you is unsure about his prayer, he should strive to do it correctly and then perform two prostrations."  

صَلَّى بِنَا رَسُولُ اللَّهِ ﷺ صَلَاةً زَادَ فِيهَا أَوْ نَقَصَ مِنْهَا فَلَمَّا أَتَمَّ قُلْنَا يَا رَسُولَ اللَّهِ أَحَدَثَ فِي الصَّلَاةِ شَيْءٌ؟ قَالَ فَثَنَى رِجْلَهُ فَسَجَدَ سَجْدَتَيْنِ ثُمَّ قَالَ « لَوْ حَدَثَ فِي الصَّلَاةِ شَيْءٌ لَأَخْبَرْتُكُمْ بِهِ وَلَكِنْ إِنَّمَا أَنَا بَشَرٌ أَنْسَى كَمَا تَنْسَوْنَ فَإِذَا نَسِيتُ فَذَكِّرُونِي وَإِذَا أَحَدُكُمْ شَكَّ فِي صَلَاتِهِ فَلْيَتَحَرَّى الصَّوَابَ وَلْيَبْنِ عَلَيْهِ ثُمَّ لْيَسْجُدْ سَجْدَتَيْنِ»

صَلَّى رَسُولُ اللهِ ﷺ صَلَاةً فَزَادَ فِيهَا أَوْ نَقَصَ فَلَمَّا قَضَى الصَّلَاةَ قَالُوا يَا رَسُولَ اللهِ هَلْ حَدَثَ فِي الصَّلَاةِ شَيْءٌ؟ قَالَ وَمَا ذَاكَ؟ قَالَ فَذَكَرْنَا الَّذِي فَعَلَ فَثَنَى رِجْلَهُ ثُمَّ اسْتَقْبَلَ الْقِبْلَةَ فَسَجَدَ سَجْدَتَيْنِ ثُمَّ أَقْبَلَ عَلَيْنَا بِوَجْهِهِ فَقَالَ لَوْ حَدَثَ فِي الصَّلَاةِ شَيْءٌ لَأَنْبَأْتُكُمْ وَإِنَّمَا أَنَا بَشَرٌ أَنْسَى كَمَا تَنْسَوْنَ فَإِذَا نَسِيتُ فَذَكِّرُونِي وَأَيُّكُمْ مَا نَسِيَ فِي صَلَاتِهِ فَلْيَتَحَرَّ الَّذِي يَرَى أَنَّهُ الصَّوَابُ فَلْيُتِمَّ عَلَيْهِ ثُمَّ يَسْجُدْ سَجْدَتَيِ السَّهْوِ  

"صَلَّى رَسُولُ الله ﷺ صَلاةً فَزَادَ أَوْ نَقَصَ، فَلَمَّا سَلَّمَ وَأَقْبَلَ عَلَى الْقَوْمِ بِوَجْههِ، قَالُوا: يَا رَسُولَ الله حَدَثَ في الصَّلَاة شَىْءٌ؟ قَالَ: وَما ذَاكَ؟ قَالَ: صَلَّيْتَ كَذَا وَكَذَا، فَثَنَى رِجْلَهُ فَسَجَدَ سَجْدَتَيْن ثُمَّ سَلَّمَ، وَأَقْبَلَ عَلَى القَوْمِ بِوَجْههِ، فَقالَ: إِنَّهُ لَوْ حَدَثَ في الصَّلَاة شَىْءٌ أنْبَأتُكُمْ به، وَلَكِنِّى بَشَرٌ، أَنْسَى كَمَا تَنْسَوْنَ، فَإِذَا نَسِيتُ فَذَكِّرُوُنى، فَإِذَا سَهَا أَحَدُكُمْ في صَلاةٍ فَلْيَتَحَرَّ الصَّوَابَ فَلْيُتِمَّ عليه، فَإِذَا سَلَّمَ سَجَدَ سَجْدَتَيْنِ".
