'Abdullah b. Buhaina al-Asadi, the ally of Abual-Muttalib, reported
The Messenger of Allah (ﷺ) stood up in the noon prayer (though) he hadith sit (after the two rak'ahs). When he completed the prayer he performed two prostrations and said," Allah is the Most Great" in each prostration, while he was sitting before pronouncing salutation, and the people performed prostration along with him. That was a compensation for he had forgotten to observe jalsa (after two rak'ahs).
وَحَدَّثَنَا قُتَيْبَةُ بْنُ سَعِيدٍ، حَدَّثَنَا لَيْثٌ، ح قَالَ وَحَدَّثَنَا ابْنُ رُمْحٍ، أَخْبَرَنَا اللَّيْثُ، عَنِ ابْنِ شِهَابٍ، عَنِ الأَعْرَجِ، عَنْ عَبْدِ اللَّهِ ابْنِ بُحَيْنَةَ الأَسْدِيِّ، حَلِيفِ بَنِي عَبْدِ الْمُطَّلِبِ أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم قَامَ فِي صَلاَةِ الظُّهْرِ وَعَلَيْهِ جُلُوسٌ فَلَمَّا أَتَمَّ صَلاَتَهُ سَجَدَ سَجْدَتَيْنِ يُكَبِّرُ فِي كُلِّ سَجْدَةٍ وَهُوَ جَالِسٌ قَبْلَ أَنْ يُسَلِّمَ وَسَجَدَهُمَا النَّاسُ مَعَهُ مَكَانَ مَا نَسِيَ مِنَ الْجُلُوسِ ‏.‏
