It was narrated from Ibn Buraidah that his father said:

"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.'"

أَخْبَرَنَا عُبَيْدُ اللَّهِ بْنُ سَعِيدٍ، قَالَ حَدَّثَنَا يَحْيَى، عَنْ سُفْيَانَ، قَالَ حَدَّثَنَا عَلْقَمَةُ بْنُ مَرْثَدٍ، عَنِ ابْنِ بُرَيْدَةَ، عَنْ أَبِيهِ، قَالَ 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 " .
