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 taslim, it was said: 'O Messenger of Allah, has there been some change concerning the prayer?' He said: 'If there had been some change concerning the prayer, I would have told you. 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 consider an estimate of what is correct, and complete his prayer on that basis, then say the taslim and prostrate twice.'"  

صَلَّى رَسُولُ اللَّهِ ﷺ فَزَادَ أَوْ نَقَصَ فَلَمَّا سَلَّمَ قُلْنَا يَا رَسُولَ اللَّهِ هَلْ حَدَثَ فِي الصَّلاَةِ شَىْءٌ قَالَ لَوْ حَدَثَ فِي الصَّلاَةِ شَىْءٌ أَنْبَأْتُكُمُوهُ وَلَكِنِّي إِنَّمَا أَنَا بَشَرٌ أَنْسَى كَمَا تَنْسَوْنَ فَأَيُّكُمْ مَا شَكَّ فِي صَلاَتِهِ فَلْيَنْظُرْ أَحْرَى ذَلِكَ إِلَى الصَّوَابِ فَلْيُتِمَّ عَلَيْهِ ثُمَّ لْيُسَلِّمْ وَلْيَسْجُدْ 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»
