Once Messenger of Allah ﷺ offered five rakʿat in the Zuhr prayer, and somebody asked him whether there was some increase in the prayer. Messenger of Allah ﷺ said, "What is that?" He said, "You have offered five rakʿat." So Messenger of Allah ﷺ performed two prostrations of Sahu after Taslim.  

أَنَّ رَسُولَ اللَّهِ ﷺ صَلَّى الظُّهْرَ خَمْسًا فَقِيلَ لَهُ أَزِيدَ فِي الصَّلاَةِ فَقَالَ وَمَا ذَاكَ قَالَ صَلَّيْتَ خَمْسًا فَسَجَدَ سَجْدَتَيْنِ بَعْدَ مَا سَلَّمَ  

The Prophet ﷺ led us in Zuhr prayer and prayer five rakʿat. Somebody asked him whether the prayer had been increased." He (the Prophet ﷺ ) said, "And what is that?" They (the people) replied, "You have prayed five rakʿat." Then the Prophet ﷺ offered two prostrations (of Sahu) after he had finished his prayer with the Taslim.  

صَلَّى بِنَا النَّبِيُّ ﷺ الظُّهْرَ خَمْسًا فَقِيلَ أَزِيدَ فِي الصَّلاَةِ قَالَ وَمَا ذَاكَ قَالُوا صَلَّيْتَ خَمْسًا فَسَجَدَ سَجْدَتَيْنِ بَعْدَ مَا سَلَّمَ  

The Messenger of Allah ﷺ prayed five rak’ahs in the noon prayer. He was asked whether the prayer had been extended. He asked what they meant by that. The people said : you prayed five rak’ahs. Then he made two prostrations after having given the salutation.  

صَلَّى رَسُولُ اللَّهِ ﷺ الظُّهْرَ خَمْسًا فَقِيلَ لَهُ أَزِيدَ فِي الصَّلاَةِ قَالَ وَمَا ذَاكَ قَالَ صَلَّيْتَ خَمْسًا فَسَجَدَ سَجْدَتَيْنِ بَعْدَ مَا سَلَّمَ  

"The Prophet (S) prayed five (Rakah) for Zuhr, so it was said to him: 'Has the prayer been added to, or have you merely forgotten?' So he (S) performed two prostrations after he had said the Salam."  

أَنَّ النَّبِيَّ ﷺ صَلَّى الظُّهْرَ خَمْسًا فَقِيلَ لَهُ أَزِيدَ فِي الصَّلاَةِ فَسَجَدَ سَجْدَتَيْنِ بَعْدَ مَا سَلَّمَ  

[Machine] About the Prophetﷺ that he prayed the noon prayer (Dhuhr) as five units. It was said to him, "Is there anything extra in the prayer?" The Prophetﷺ said, "What is that?" They said, "You prayed five units." Then he performed two additional prostrations after the prayer.  

عَنِ النَّبِيِّ ﷺ أَنَّهُ صَلَّى الظُّهْرَ خَمْسًا فَقِيلَ زِيدَ فِي الصَّلَاةِ شَيْءٌ؟ فَقَالَ النَّبِيُّ ﷺ «وَمَا ذَاكَ؟ » قَالُوا إِنَّكَ صَلَّيْتَ خَمْسًا فَسَجَدَ سَجْدَتَيْنِ بَعْدَمَا سَلَّمَ  

[Machine] From the Prophet ﷺ, it was narrated that he prayed Dhuhr prayer five units. It was asked, "Was anything added in the prayer, O Messenger of Allah?" He ﷺ said, "What is that?" It was said, "Verily, you prayed five units, then you prostrated twice after making the salaam."  

عَنِ النَّبِيِّ ﷺ أَنَّهُ صَلَّى الظُّهْرَ خَمْسًا فَقِيلَ زِيدَ فِي الصَّلَاةِ شَيْءٌ؟ فَقَالَ النَّبِيُّ ﷺ «وَمَا ذَاكَ؟ » قَالَ إِنَّكَ صَلَّيْتَ خَمْسًا فَسَجَدَ سَجْدَتَيْنِ بَعْدَمَا سَلَّمَ  

The Prophet ﷺ led them in praying Zuhr with five (rak'ahs). They said: 'You prayed five.' So he prostrated twice after he had said the taslim, while he was sitting. (Using translation from Nasāʾī 1255)  

عَنِ النَّبِيِّ ﷺ أَنَّهُ صَلَّى بِهِمُ الظُّهْرَ خَمْسًا فَقَالُوا إِنَّكَ صَلَّيْتَ خَمْسًا «فَسَجَدَ سَجْدَتَيْنِ بَعْدَمَا سَلَّمَ وَهُوَ جَالِسٌ»  

[Machine] The Prophet ﷺ prayed Dhuhr with them five times, and they said, "You prayed five times." He then prostrated twice after the salaam while he was sitting. 583 Qutaibah ibn Sa'eed informed us, he said: Abu Awana narrated to us from Mughirah, from Ibrahim, that the Prophet ﷺ prayed while he was musallam (i.e. not leading the prayer).  

عَنِ النَّبِيِّ ﷺ أَنَّهُ صَلَّى بِهِمُ الظُّهْرَ خَمْسًا فَقَالُوا إِنَّكَ صَلَّيْتَ خَمْسًا فَسَجَدَ سَجْدَتَيْنِ بَعْدَمَا سَلَّمَ وَهُوَ جَالِسٌ 583 أَخْبَرَنَا قُتَيْبَةُ بْنُ سَعِيدٍ قَالَ حَدَّثَنَا أَبُو عَوَانَةَ عَنْ مُغِيرَةَ عَنْ إِبْرَاهِيمَ أَنَّ النَّبِيَّ ﷺ صَلَّى مُرْسَلٌ  

"صَلَّى النَّبِىُّ ﷺ الظُّهْرَ خَمْسًا، فَقيلَ لَهُ: إِنَّكَ صَلَّيْتَ خَمْسًا، فَسَجَدَ سَجْدتَيْنِ بَعْدَمَا سَلَّمَ".
