'The Messenger of Allah ﷺ did not prostrate that day either before the salam or after." (Using translation from Nasāʾī 1232)  

أَنَّهُ «لَمْ يَسْجُدْ رَسُولُ اللهِ ﷺ يَوْمَئِذٍ قَبْلَ السَّلَامِ وَلَا بَعْدَهُ»  

[Machine] The Messenger of Allah, ﷺ , performed two prostrations after the prayer. Narrated by Amr ibn Sawad, who narrated from Ibn Wahb, who narrated from Amr ibn Al-Harith, who narrated from Qatadah, who narrated from Muhammad ibn Sireen, who narrated from Abu Huraira, who narrated from the Messenger of Allah, ﷺ , with the same wording.  

أَنَّ رَسُولَ اللهِ ﷺ «سَجَدَ يَوْمَ ذِي الْيَدَيْنِ سَجْدَتَيْنِ بَعْدَ السَّلَامِ» 1158 أَخْبَرَنَا عَمْرُو بْنُ سَوَادٍ قَالَ أَخْبَرَنَا ابْنُ وَهْبٍ أَخْبَرَنَا عَمْرُو بْنُ الْحَارِثِ قَالَ حَدَّثَنِي قَتَادَةُ عَنْ مُحَمَّدِ بْنِ سِيرِينَ عَنْ أَبِي هُرَيْرَةَ عَنْ رَسُولِ اللهِ ﷺ بِمِثْلِهِ  

The Prophet ﷺ prostrated after the salam when he was not sure. (Using translation from Nasāʾī 1235)  

أَنَّ النَّبِيَّ ﷺ «سَجَدَ فِي وَهْمِهِ بَعْدَ التَّسْلِيمِ»  

The Prophet ﷺ led them in prayer and forgot something, so he made prostrations and uttered the tashahhud, then gave the salutation. (Using translation from Abū Dāʾūd 1039)   

أَنَّ النَّبِيَّ ﷺ «صَلَّى بِهِمْ فَسَهَا فَسَجَدَ ثُمَّ سَلَّمَ»  

"The Messenger of Allah ﷺ said the salam after three rak'ahs of 'Asr, then he entered his house. A man called Al-Khibaq stood up and said: 'Has the prayer been shortened, O Messenger of Allah?' He came out angry, dragging his upper garment and said: 'Is he speaking the truth?' They said: 'Yes.' So he stood and prayed that rak'ah, then he said the salam, then prostrated twice, then he said the salam (again)." (Using translation from Nasāʾī 1237)  

سَلَّمَ النَّبِيُّ ﷺ فِي ثَلَاثِ رَكَعَاتٍ مِنَ الْعَصْرِ فَدَخَلَ فَقَامَ إِلَيْهِ رَجُلٌ يُقَالُ لَهُ الْخِرْبَاقُ فَقَالَ الصَّلَاةُ يَا رَسُولَ اللهِ فَخَرَجَ مُغْضَبًا يَجُرُّ رِدَاءَهُ فَقَالَ «أَصَدَقَ» قَالُوا نَعَمْ فَقَامَ «فَصَلَّى تِلْكَ الرَّكْعَةَ ثُمَّ سَلَّمَ ثُمَّ سَجَدَ سَجْدَتَيْهَا ثُمَّ سَلَّمَ»
