Anas said, "The Prophet ﷺ used to perform ablution for every prayer." I asked Anas, "What did you used to do?' Anas replied, "We used to pray with the same ablution until we break it with Hadath."  

كَانَ النَّبِيُّ ﷺ يَتَوَضَّأُ عِنْدَ كُلِّ صَلاَةٍ قُلْتُ كَيْفَ كُنْتُمْ تَصْنَعُونَ قَالَ يُجْزِئُ أَحَدَنَا الْوُضُوءُ مَا لَمْ يُحْدِثْ  

I asked Anas b. Malik about ablution. He replied: The Prophet ﷺ performed ablution for each prayer and we offered (many) prayers with the same ablution.  

كَانَ النَّبِيُّ ﷺ يَتَوَضَّأُ لِكُلِّ صَلاَةٍ وَكُنَّا نُصَلِّي الصَّلَوَاتِ بِوُضُوءٍ وَاحِدٍ  

"The Prophet would perform Wudu for every Salat." I said, "So what about you, what would you do?" He said I wouId pray all of the prayers with one Wudu, as long as we had not committed Hadath (anything that invalidates Wudu)."  

سَمِعْتُ أَنَسَ بْنَ مَالِكٍ يَقُولُ كَانَ النَّبِيُّ ﷺ يَتَوَضَّأُ عِنْدَ كُلِّ صَلاَةٍ قُلْتُ فَأَنْتُمْ مَا كُنْتُمْ تَصْنَعُونَ قَالَ كُنَّا نُصَلِّي الصَّلَوَاتِ كُلَّهَا بِوُضُوءٍ وَاحِدٍ مَا لَمْ نُحْدِثْ  

"The Prophet would perform Wudu for every Salat." I said, "So what about you, what would you do?" He said I wouId pray all of the prayers with one Wudu, as long as we had not committed Hadath (anything that invalidates Wudu)." (Using translation from Tirmidhī 60)   

سَمِعْتُ أَنَسًا يَقُولُ كَانَ رَسُولُ اللهِ ﷺ يَتَوَضَّأُ عِنْدَ كُلِّ صَلَاةٍ قَالَ قُلْتُ وَأَنْتُمْ كَيْفَ كُنْتُمْ تَصْنَعُونَ؟ قَالَ كُنَّا نُصَلِّي الصَّلَوَاتِبِوُضُوءٍ وَاحِدٍ مَا لَمْ نُحْدِثْ  

"The Messenger of Allah used to perform ablution for every prayer, and we used to perform all of the prayers with one ablution." (Using translation from Ibn Mājah 509)   

«كَانَ رَسُولُ اللَّهِ ﷺ يَتَوَضَّأُ لِكُلِّ صَلَاةٍ فَلَمَّا كَانَ يَوْمُ فَتْحِ مَكَّةَ صَلَّى الصَّلَوَاتِ كُلَّهَا بِوَضُوءٍ وَاحِدٍ»
