Narrated Abu Huraira: Allah's Messenger (ﷺ) finished his prayer after offerings two rak`at only. Dhul-Yaddain asked him whether the prayer had been reduced, or you had forgotten?" The Prophet (ﷺ) said, "Is Dhul-Yaddain speaking the truth?" The people said, "Yes." Then Allah's Messenger (ﷺ) stood up and performed another two rak`at and then finished prayer with Taslim, and then said the Takbir and performed a prostration similar to or longer than his ordinary prostrations; then he raised his head, said Takbir and prostrated and then raised his head (Sahu prostrations).

حَدَّثَنَا إِسْمَاعِيلُ، حَدَّثَنِي مَالِكٌ، عَنْ أَيُّوبَ، عَنْ مُحَمَّدٍ، عَنْ أَبِي هُرَيْرَةَ، أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم انْصَرَفَ مِنِ اثْنَتَيْنِ فَقَالَ لَهُ ذُو الْيَدَيْنِ أَقَصُرَتِ الصَّلاَةُ يَا رَسُولَ اللَّهِ، أَمْ نَسِيتَ فَقَالَ ‏ "‏ أَصَدَقَ ذُو الْيَدَيْنِ ‏"‏‏.‏ فَقَالَ النَّاسُ نَعَمْ‏.‏ فَقَامَ رَسُولُ اللَّهِ صلى الله عليه وسلم فَصَلَّى رَكْعَتَيْنِ أُخْرَيَيْنِ، ثُمَّ سَلَّمَ، ثُمَّ كَبَّرَ، ثُمَّ سَجَدَ مِثْلَ سُجُودِهِ أَوْ أَطْوَلَ، ثُمَّ رَفَعَ، ثُمَّ كَبَّرَ، فَسَجَدَ مِثْلَ سُجُودِهِ، ثُمَّ رَفَعَ‏.‏
