[Machine] The Messenger of Allah ﷺ stood up for the Dhuhr prayer while he was sitting. When he completed his prayer, he performed two prostrations, saying takbir in each prostration, while he was still sitting, before making the Salam. The people also performed these two prostrations along with him wherever they were sitting. The narration did not mention any difference in their sitting positions except that Abu 'Amr did not say 'As-Saddi (As-Saddi is the name of the place where the Prophet had made the prostrations), nor did he say Halif bin 'Abdul-Muttalib.  

أَنَّ رَسُولَ اللهِ ﷺ قَامَ فِي صَلَاةِ الظُّهْرِ وَعَلَيْهِ جُلُوسٌ فَلَمَّا أَتَمَّ صَلَاتَهُ سَجَدَ سَجْدَتَيْنِ يُكَبِّرُ فِي كُلِّ سَجْدَةٍ وَهُوَ جَالِسٌ قَبْلَ أَنْ يُسَلِّمَ وَسَجَدَهُمَا النَّاسُ مَعَهُ مَكَانَ مَا نَسِيَ مِنَ الْجُلُوسِ لَفْظُ حَدِيثِهِمَا سَوَاءٌ إِلَّا أَنَّ أَبَا عَمْرٍو لَمْ يَقُلْ الْأَسَدِيِّ وَلَا حَلِيفِ بَنِي عَبْدِ الْمُطَّلِبِ  

[Machine] The Messenger of Allah ﷺ stood up from sitting and he said, "wait for his peace". Then he said the takbeer, then he prostrated, then said the takbeer again, then raised his head, then said the takbeer again, then prostrated, then said the takbeer again, then raised his head, and then said the peace.  

أَنَّ رَسُولَ اللهِ ﷺ سَهَا عَنْ قُعُودٍ قَامَ عَنْهُ قَالَ فَانْتَظَرْنَا سَلَامَهُ فَكَبَّرَ ثُمَّ سَجَدَ ثُمَّ كَبَّرَ فَرَفَعَ رَأْسَهُ ثُمَّ كَبَّرَ فَسَجَدَ ثُمَّ كَبَّرَ فَرَفَعَ رَأْسَهُ ثُمَّ سَلَّمَ
