Once Messenger of Allah ﷺ led us in prayer, and after finishing the first two rakʿat, got up (instead of sitting for at-Tahiyyat) and then carried on with the prayer. When he had finished his prayer, the people were waiting for him to say Taslim, but before saying Tasiim, he said Takbir and prostrated; then he raised his head, and saying Takbir, he prostrated (SAHU) and then raised his head and finished his prayer with Taslim.  

البخاري:٦٦٧٠حَدَّثَنَا آدَمُ بْنُ أَبِي إِيَاسٍ حَدَّثَنَا ابْنُ أَبِي ذِئْبٍ عَنِ الزُّهْرِيِّ عَنِ الأَعْرَجِ عَنْ عَبْدِ اللَّهِ ابْنِ بُحَيْنَةَ قَالَ

صَلَّى بِنَا النَّبِيُّ ﷺ فَقَامَ فِي الرَّكْعَتَيْنِ الأُولَيَيْنِ قَبْلَ أَنْ يَجْلِسَ فَمَضَى فِي صَلاَتِهِ فَلَمَّا قَضَى صَلاَتَهُ انْتَظَرَ النَّاسُ تَسْلِيمَهُ وَسَجَدَ قَبْلَ أَنْ يُسَلِّمَ ثُمَّ رَفَعَ رَأْسَهُ ثُمَّ كَبَّرَ وَسَجَدَ ثُمَّ رَفَعَ رَأْسَهُ وَسَلَّمَ

The Messenger of Allah ﷺ led us in prayer praying two rak'ahs. When he stood up and did not sit (at the end of two rak'ahs) the people stood up along with him. When he finished the prayer and we expect him to give the salutation, he said: "Allah is most great." While sitting and made two prostrations before giving the salutation. Then he gave it.  

أبو داود:١٠٣٤حَدَّثَنَا الْقَعْنَبِيُّ عَنْ مَالِكٍ عَنِ ابْنِ شِهَابٍ عَنْ عَبْدِ الرَّحْمَنِ الأَعْرَجِ عَنْ عَبْدِ اللَّهِ ابْنِ بُحَيْنَةَ

أَنَّهُ قَالَ صَلَّى لَنَا رَسُولُ اللَّهِ ﷺ رَكْعَتَيْنِ ثُمَّ قَامَ فَلَمْ يَجْلِسْ فَقَامَ النَّاسُ مَعَهُ فَلَمَّا قَضَى صَلاَتَهُ وَانْتَظَرْنَا التَّسْلِيمَ كَبَّرَ فَسَجَدَ سَجْدَتَيْنِ وَهُوَ جَالِسٌ قَبْلَ التَّسْلِيمِ ثُمَّ سَلَّمَ ﷺ
