Sahih al-Bukhari 829
Narrated `Abdullah bin Buhaina:
(he was from the tribe of Uzd Shanu'a [??] and was the ally of the tribe of `Abdul-Manaf and was one 
of the companions of the Prophet): Once the Prophet (ﷺ) led us in the Zuhr prayer and stood up after the 
second rak`a and did not sit down. The people stood up with him. When the prayer was about to end 
and the people were waiting for him to say the Taslim, he said Takbir while sitting and prostrated 
twice before saying the Taslim and then he said the Taslim."
حَدَّثَنَا أَبُو الْيَمَانِ، قَالَ أَخْبَرَنَا شُعَيْبٌ، عَنِ الزُّهْرِيِّ، قَالَ حَدَّثَنِي عَبْدُ الرَّحْمَنِ بْنُ هُرْمُزَ، مَوْلَى بَنِي عَبْدِ الْمُطَّلِبِ ـ وَقَالَ مَرَّةً مَوْلَى رَبِيعَةَ بْنِ الْحَارِثِ ـ أَنَّ عَبْدَ اللَّهِ ابْنَ بُحَيْنَةَ ـ وَهْوَ مِنْ أَزْدِ شَنُوءَةَ وَهْوَ حَلِيفٌ لِبَنِي عَبْدِ مَنَافٍ، وَكَانَ مِنْ أَصْحَابِ النَّبِيِّ صلى الله عليه وسلم‏.‏ أَنَّ النَّبِيَّ صلى الله عليه وسلم صَلَّى بِهِمُ الظُّهْرَ فَقَامَ فِي الرَّكْعَتَيْنِ الأُولَيَيْنِ لَمْ يَجْلِسْ، فَقَامَ النَّاسُ مَعَهُ حَتَّى إِذَا قَضَى الصَّلاَةَ، وَانْتَظَرَ النَّاسُ تَسْلِيمَهُ، كَبَّرَ وَهْوَ جَالِسٌ، فَسَجَدَ سَجْدَتَيْنِ قَبْلَ أَنْ يُسَلِّمَ ثُمَّ سَلَّمَ‏.‏
