Once Messenger of Allah ﷺ prayed two rakʿat (instead of four) and finished his prayer. Dhul-Yadain asked him whether the prayer had been reduced or whether he had forgotten. Messenger of Allah ﷺ asked the people whether Dhul-Yadain was telling the truth. The people replied in the affirmative. Then Allah's Apostle stood up, offered the remaining two rakʿat and then finished his prayer with Taslim and then said, "Allahu Akbar." He followed it with two prostrations like ordinary prostrations or a bit longer.  

أَنَّ رَسُولَ اللَّهِ ﷺ انْصَرَفَ مِنَ اثْنَتَيْنِ فَقَالَ لَهُ ذُو الْيَدَيْنِ أَقَصُرَتِ الصَّلاَةُ أَمْ نَسِيتَ يَا رَسُولَ اللَّهِ فَقَالَ رَسُولُ اللَّهِ ﷺ أَصَدَقَ ذُو الْيَدَيْنِ فَقَالَ النَّاسُ نَعَمْ فَقَامَ رَسُولُ اللَّهِ ﷺ فَصَلَّى اثْنَتَيْنِ أُخْرَيَيْنِ ثُمَّ سَلَّمَ ثُمَّ كَبَّرَ فَسَجَدَ مِثْلَ سُجُودِهِ أَوْ أَطْوَلَ  

Messenger of Allah ﷺ finished his prayer after offerings two rakʿat 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 Messenger of Allah ﷺ stood up and performed another two rakʿat 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).  

أَنَّ رَسُولَ اللَّهِ ﷺ انْصَرَفَ مِنِ اثْنَتَيْنِ فَقَالَ لَهُ ذُو الْيَدَيْنِ أَقَصُرَتِ الصَّلاَةُ يَا رَسُولَ اللَّهِ أَمْ نَسِيتَ فَقَالَ أَصَدَقَ ذُو الْيَدَيْنِ فَقَالَ النَّاسُ نَعَمْ فَقَامَ رَسُولُ اللَّهِ ﷺ فَصَلَّى رَكْعَتَيْنِ أُخْرَيَيْنِ ثُمَّ سَلَّمَ ثُمَّ كَبَّرَ ثُمَّ سَجَدَ مِثْلَ سُجُودِهِ أَوْ أَطْوَلَ ثُمَّ رَفَعَ ثُمَّ كَبَّرَ فَسَجَدَ مِثْلَ سُجُودِهِ ثُمَّ رَفَعَ  

The Messenger of Allah ﷺ finished praying two rak'ahs,and Dhul-Yadain said to him: "Has the prayer been shortened or did you forget, O Messenger of Allah?" The Messenger of Allah ﷺ said: "Is Dhul-Yadain speaking the truth?" The people said: "Yes." So the Messenger of Allah ﷺ stood up and prayed two, then he said the takbir and prostrated as usual or longer than that. Then he raised his head, then he prostrated as usual or longer than that, then he sat up."  

أَنَّ رَسُولَ اللَّهِ ﷺ انْصَرَفَ مِنَ اثْنَتَيْنِ فَقَالَ لَهُ ذُو الْيَدَيْنِ أَقُصِرَتِ الصَّلاَةُ أَمْ نَسِيتَ يَا رَسُولَ اللَّهِ فَقَالَ رَسُولُ اللَّهِ ﷺ أَصَدَقَ ذُو الْيَدَيْنِ فَقَالَ النَّاسُ نَعَمْ فَقَامَ رَسُولُ اللَّهِ ﷺ فَصَلَّى اثْنَتَيْنِ ثُمَّ سَلَّمَ ثُمَّ كَبَّرَ فَسَجَدَ مِثْلَ سُجُودِهِ أَوْ أَطْوَلَ ثُمَّ رَفَعَ رَأْسَهُ ثُمَّ سَجَدَ مِثْلَ سُجُودِهِ أَوْ أَطْوَلَ ثُمَّ رَفَعَ  

"The Prophet (S) turned (finished the prayer) after two (Rak'ah), so Dhul-Yadain said: 'Has the prayer been shortened or have you forgotten O Messenger of Allah?" The Prophet (S) said: 'Is what Dhul-Yadain said the truth?' The people said yes, so Messenger of Allah (S) stood to perform the last two (Rakah) of Salat, then he said the Taslim. Then he said the Takbir and prostrated in a manner the same or longer than his (normal) prostrations."  

أَنَّ النَّبِيَّ ﷺ انْصَرَفَ مِنَ اثْنَتَيْنِ فَقَالَ لَهُ ذُو الْيَدَيْنِ أَقُصِرَتِ الصَّلاَةُ أَمْ نَسِيتَ يَا رَسُولَ اللَّهِ فَقَالَ رَسُولُ اللَّهِ ﷺ أَصَدَقَ ذُو الْيَدَيْنِ فَقَالَ النَّاسُ نَعَمْ فَقَامَ رَسُولُ اللَّهِ ﷺ فَصَلَّى اثْنَتَيْنِ أُخْرَيَيْنِ ثُمَّ سَلَّمَ ثُمَّ كَبَّرَ فَسَجَدَ مِثْلَ سُجُودِهِ أَوْ أَطْوَلَ ثُمَّ كَبَّرَ فَرَفَعَ ثُمَّ سَجَدَ مِثْلَ سُجُودِهِ أَوْ أَطْوَلَ  

Yahya related to me from Malik from Ayyub ibn Abi Tamima as- Sakhtayani from Muhammad ibn Sirin from Abu Hurayra that the Messenger of Allah ﷺ finished the prayer after two rakas and Dhu'l-Yadayn said to him, "Has the prayer been shortened or have you forgotten, Messenger of Allah?" The Messenger of Allah ﷺ said, "Has Dhu'l-Yadayn spoken the truth?" The people said, "Yes," and the Messenger of Allah ﷺ stood and prayed the other two rakas and then said, "Peace be upon you." Then he said, "Allah is greater" and went into a sadja as long as his usual prostrations or longer. Then he came up and said, "Allah is greater" and went into a sajda as long as his usual prostrations or longer and then came up.

[Machine] That the Messenger of Allah ﷺ turned away from two people, so the one with two hands said to him, "Did the prayer become shorter or did you forget, O Messenger of Allah?" So the Messenger of Allah ﷺ said, "Did the one with two hands speak the truth?" So the people said, "Yes." So the Messenger of Allah ﷺ stood up and prayed two more units of prayer, then he made the greeting (salam), then he made the takbir (saying Allahu Akbar), then he prostrated the same length as his prostration or longer, then he raised his head and made the takbir, then he prostrated the same length as his prostration or longer. Then he said, "The wording of their hadith is the same, except that Ash-Shafi'i, may Allah have mercy on him, did not say 'the son of Abu Tamimah."
