"The Messenger of Allah ﷺ used to perform Wudu' for every prayer. One the day of the Conquest (of Makkah), he offered all the prayers with one Wudu'. 'Umar said to him: 'You have done something that you never did before.' He said: 'I did that deliberately, O 'Umar.'"  

كَانَ رَسُولُ اللَّهِ ﷺ يَتَوَضَّأُ لِكُلِّ صَلاَةٍ فَلَمَّا كَانَ يَوْمُ الْفَتْحِ صَلَّى الصَّلَوَاتِ بِوُضُوءٍ وَاحِدٍ فَقَالَ لَهُ عُمَرُ فَعَلْتَ شَيْئًا لَمْ تَكُنْ تَفْعَلُهُ قَالَ عَمْدًا فَعَلْتُهُ يَا عُمَرُ  

"The Prophet would perform Wudu for every Salat. So during the year of the Conquest, he performed all of the prayers with one Wudu, and he wiped over his Khuff. So Umar said, 'You did something that you have not done before?' He replied: "I did it on purpose."  

كَانَ النَّبِيُّ ﷺ يَتَوَضَّأُ لِكُلِّ صَلاَةٍ فَلَمَّا كَانَ عَامُ الْفَتْحِ صَلَّى الصَّلَوَاتِ كُلَّهَا بِوُضُوءٍ وَاحِدٍ وَمَسَحَ عَلَى خُفَّيْهِ فَقَالَ عُمَرُ إِنَّكَ فَعَلْتَ شَيْئًا لَمْ تَكُنْ فَعَلْتَهُ قَالَ عَمْدًا فَعَلْتُهُ  

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»  

"The Messenger of Allah ﷺ used to perform Wudu' for every prayer. One the day of the Conquest (of Makkah), he offered all the prayers with one Wudu'. 'Umar said to him: 'You have done something that you never did before.' He said: 'I did that deliberately, O 'Umar.'" (Using translation from Nasāʾī 133)  

كَانَ رَسُولُ اللهِ ﷺ يَتَوَضَّأُ لِكُلِّ صَلَاةٍ فَلَمَّا كَانَ يَوْمُ الْفَتْحِ صَلَّى الصَّلَوَاتُ بِوُضُوءٍ وَاحِدٍ فَقَالَ لَهُ عُمَرُ فَعَلْتَ شَيْئًا لَمْ تَكُنْ تَفْعَلُهُ فَقَالَ «عَمْدًا فَعَلْتُهُ يَا عُمَرُ»
