حَدَّثَنَا الْقَعْنَبِيُّ، عَنْ مَالِكٍ، عَنِ ابْنِ شِهَابٍ، عَنْ عَبْدِ الرَّحْمَنِ الأَعْرَجِ، عَنْ عَبْدِ اللَّهِ ابْنِ بُحَيْنَةَ، أَنَّهُ قَالَصَلَّى لَنَا رَسُولُ اللَّهِ صلى الله عليه وسلم رَكْعَتَيْنِ ثُمَّ قَامَ فَلَمْ يَجْلِسْ فَقَامَ النَّاسُ مَعَهُ فَلَمَّا قَضَى صَلاَتَهُ وَانْتَظَرْنَا التَّسْلِيمَ كَبَّرَ فَسَجَدَ سَجْدَتَيْنِ وَهُوَ جَالِسٌ قَبْلَ التَّسْلِيمِ ثُمَّ سَلَّمَ صلى الله عليه وسلم ‏.‏
Translation
Narrated Abdullah ibn Buhaynah

The Messenger of Allah (ﷺ) led us in prayer, praying two rak'ahs, then he stood up and did not sit. The people stood up with him, and when he finished his prayer and we waited for the taslim, he pronounced the takbir and prostrated twice while sitting before the taslim, then he gave the taslim.
