“The Prophet ﷺ offered prayer, I think it was the ‘Asr, and in the second Rak’ah he stood up before he sat. Before he said the Salam, he prostrated twice.”  

أَنَّ النَّبِيَّ ﷺ صَلَّى صَلاَةً أَظُنُّ أَنَّهَا الظُّهْرُ (العَصْرُ) فَلَمَّا كَانَ فِي الثَّانِيَةِ قَامَ قَبْلَ أَنْ يَجْلِسَ فَلَمَّا كَانَ قَبْلَ أَنْ يُسَلِّمَ سَجَدَ سَجْدَتَيْنِ  

[Machine] Ibn Buhaynah narrated that the Messenger of Allah ﷺ prayed a prayer with us that we thought was 'Asr prayer. He stood up in the second (rak'ah) and did not sit down. When it was before he finished, he prostrated twice.  

عَنِ ابْنِ بُحَيْنَةَ صَلَّى بِنَا رَسُولُ اللهِ ﷺ صَلَاةً نَظُنُّ أَنَّهَا الْعَصْرُ فَقَامَ فِي الثَّانِيَةِ لَمْ يَجْلِسْ فَلَمَّا كَانَ قَبْلَ أَنْ يُسَلِّمَ سَجَدَ سَجْدَتَيْنِ
