You have today done something that you have not been accustomed to before. He (the Holy Prophet) said: 0 'Umar, I have done that on purpose.  

أَنَّ النَّبِيَّ ﷺ صَلَّى الصَّلَوَاتِ يَوْمَ الْفَتْحِ بِوُضُوءٍ وَاحِدٍ وَمَسَحَ عَلَى خُفَّيْهِ فَقَالَ لَهُ عُمَرُ لَقَدْ صَنَعْتَ الْيَوْمَ شَيْئًا لَمْ تَكُنْ تَصْنَعُهُ قَالَ عَمْدًا صَنَعْتُهُ يَا عُمَرُ  

The Messenger of Allah ﷺ performed five prayers with the same ablution of the occasion of the capture of Mecca, and he wiped over his socks. ‘Umar said to him(the Prophet): I saw you doing a thing today that you never did. He said: I did it deliberately.  

صَلَّى رَسُولُ اللَّهِ ﷺ يَوْمَ الْفَتْحِ خَمْسَ صَلَوَاتٍ بِوُضُوءٍ وَاحِدٍ وَمَسَحَ عَلَى خُفَّيْهِ فَقَالَ لَهُ عُمَرُ إِنِّي رَأَيْتُكَ صَنَعْتَ الْيَوْمَ شَيْئًا لَمْ تَكُنْ تَصْنَعُهُ قَالَ عَمْدًا صَنَعْتُهُ  

[Machine] "When the Messenger of Allah ﷺ conquered Mecca on the day of victory, he performed ablution and wiped over his socks. 'Umar said to him, 'O Messenger of Allah, today I saw you doing something that you do not normally do.' He replied, 'I did it intentionally, O Umar.'"  

أَنَّ رَسُولَ اللهِ ﷺ لَمَّا كَانَ يَوْمُ الْفَتْحِ فَتْحُ مَكَّةَ تَوَضَّأَ وَمَسَحَ عَلَى خُفَّيْهِ فَقَالَ لَهُ عُمَرُ رَأَيْتُكَ يَا رَسُولَ اللهِ صَنَعْتَ الْيَوْمَ شَيْئًا لَمْ تَكُنْ تَصْنَعُهُ قَالَ عَمْدًا صَنَعْتُهُ يَا عُمَرُ  

The Messenger of Allah ﷺ performed five prayers with the same ablution of the occasion of the capture of Mecca, and he wiped over his socks. ‘Umar said to him(the Prophet): I saw you doing a thing today that you never did. He said: I did it deliberately. (Using translation from Abū Dāʾūd 172)   

«صَلَّى رَسُولُ اللَّهِ ﷺ الصَّلَوَاتِ كُلَّهَا يَوْمَ فَتْحِ مَكَّةَ بِوَضُوءٍ وَاحِدٍ وَمَسَحَ عَلَى خُفَّيْهِ» فَقَالَ لَهُ عُمَرُ إِنِّي رَأَيْتُكَ الْيَوْمَ صَنَعْتَ شَيْئًا لَمْ تَكُنْ تَصْنَعُهُ قَبْلَ الْيَوْمِ قَالَ «عَمْدًا فَعَلْتُ يَا عُمَرُ»
