[Machine] The Messenger of Allah ﷺ said, "Whoever doubts about his prayer, let him prostrate twice after he has finished the prayer. This narration is acceptable except that the narration of Abu Sa'id Al-Khudri is more authentic, along with the narration of Abdul Rahman ibn Awf and Abu Hurairah, according to what we mentioned. And Allah knows best."  

أَنَّ رَسُولَ اللهِ ﷺ قَالَ مَنْ شَكَّ فِي صَلَاتِهِ فَلْيَسْجُدْ سَجْدَتَيْنِ بَعْدَ أَنْ يُسَلِّمَ هَذَا الْإِسْنَادُ لَا بَأْسَ بِهِ إِلَّا أَنَّ حَدِيثَ أَبِي سَعِيدٍ الْخُدْرِيِّ أَصَحُّ إِسْنَادًا مِنْهُ وَمَعَهُ حَدِيثُ عَبْدِ الرَّحْمَنِ بْنِ عَوْفٍ وَأَبِي هُرَيْرَةَ عَلَى مَا نَذْكُرُهُ وَاللهُ أَعْلَمُ  

[Machine] About the Prophet ﷺ , he said that for every mistake, there are two prostrations after saying the salaam. Abu Ali Al-Rawdhbari reported to us that Abu Bakr ibn Dasa narrated from Abu Dawud, who narrated from Amr ibn Uthman and Al-Rabi bin Nafi' who narrated from Uthman ibn Abi Shaybah and Shuja' ibn Makhlad that Ibn Ayyash narrated to them and mentioned it in a similar manner, except that he did not mention it from his father except from Amr ibn Uthman. Zuhair, meaning Ibn Salim Al-Ansi, commented that this chain of narration is weak. The hadith of Abu Hurayrah, Imran, and others about the gathering of a number of mistakes on the Prophet ﷺ , then settling on the two prostrations contradicts this. And Allah knows best.  

عَنِ النَّبِيِّ ﷺ قَالَ لِكُلِّ سَهْوٍ سَجْدَتَانِ بَعْدَ مَا يُسَلِّمُ 3823 وَأَخْبَرَنَا أَبُو عَلِيٍّ الرُّوذْبَارِيُّ أنبأ أَبُو بَكْرِ بْنُ دَاسَةَ ثنا أَبُو دَاوُدَ ثنا عَمْرُو بْنُ عُثْمَانَ وَالرَّبِيعُ بْنُ نَافِعٍ عَنْ عُثْمَانَ بْنِ أَبِي شَيْبَةَ وَشُجَاعِ بْنِ مَخْلَدٍ أَنَّ ابْنَ عَيَّاشٍ حَدَّثَهُمْ فَذَكَرَهُ بِنَحْوِهِ إِلَّا أَنَّهُ لَمْ يَذْكُرْ عَنْ أَبِيهِ غَيْرُ عَمْرِو بْنِ عُثْمَانَ وَقَالَ زُهَيْرٌ يَعْنِي ابْنَ سَالِمٍ الْعَنْسِيَّ وَهَذَا إِسْنَادٌ فِيهِ ضِعْفٌ وَحَدِيثُ أَبِي هُرَيْرَةَ وَعِمْرَانَ وَغَيْرِهِمَا فِي اجْتِمَاعِ عَدَدٍ مِنَ السَّهْوِ عَلَى النَّبِيِّ ﷺ ثُمَّ اقْتَصَارُهُ عَلَى السَّجْدَتَيْنِ يُخَالِفُ هَذَا وَاللهُ أَعْلَمُ  

[Machine] Al-Mughira led us in prayer and then stood up for the two extra rak'at (units of prayer). We said, "Subhanallah" (glory be to Allah). He said, "Subhanallah" and moved on. When he completed his prayer and gave the salutations, he performed the two prostrations of forgetfulness. When he finished, he said, "I saw the Messenger of Allah ﷺ doing as I did." Abu Dawud said, "And likewise."  

صَلَّى بِنَا الْمُغِيرَةُ فَنَهَضَ فِي الرَّكْعَتَيْنِ قُلْنَا سُبْحَانَ اللهِ قَالَ سُبْحَانَ اللهِ وَمَضَى فَلَمَّا أَتَمَّ صَلَاتَهُ وَسَلَّمَ سَجَدَ سَجْدَتَيِ السَّهْوِ فَلَمَّا انْصَرَفَ قَالَ رَأَيْتُ رَسُولَ اللهِ ﷺ يَصْنَعُ كَمَا صَنَعْتُ قَالَ أَبُو دَاوُدَ وَكَذَلِكَ
