"The Messenger of Allah ﷺ was brought a small vessel (of water) and he performed Wudu'." I said: "Did the Messenger of Allah ﷺ perform Wudu' for every prayer?" He said: "Yes." He said: "What about you?" He said: "We used to pray all the prayers so long as we did not commit Hadath." He said: "And we used to pray all the prayers with (one) Wudu'."  

أَنَّ النَّبِيَّ ﷺ أُتِيَ بِإِنَاءٍ صَغِيرٍ فَتَوَضَّأَ قُلْتُ أَكَانَ النَّبِيُّ ﷺ يَتَوَضَّأُ لِكُلِّ صَلاَةٍ قَالَ نَعَمْ قَالَ فَأَنْتُمْ قَالَ كُنَّا نُصَلِّي الصَّلَوَاتِ مَا لَمْ نُحْدِثْ قَالَ وَقَدْ كُنَّا نُصَلِّي الصَّلَوَاتِ بِوُضُوءٍ  

"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  

[Machine] I heard Anas bin Malik say that the Prophet ﷺ was given a cup of water, so he performed ablution. Umar said, "I said to Anas, 'Did he perform ablution with every prayer?' He said, 'Yes.' I said, 'And what about you?' He said, 'We used to pray the prayers with one ablution.' Then I asked him again, and he said, 'Unless we broke it.'"  

سَمِعْتُ أَنَسَ بْنَ مَالِكٍ يَقُولُ إِنَّ النَّبِيَّ ﷺ أُتِيَ بِقَدَحٍ مِنْ مَاءٍ فَتَوَضَّأَ قَالَ عَمْرٌو قُلْتُ لِأَنَسٍ أَكَانَ يَتَوَضَّأُ عِنْدَ كُلِّ صَلَاةٍ؟ قَالَ نَعَمْ قُلْتُ فَأَنْتُمْ؟ قَالَ كُنَّا نُصَلِّي الصَّلَوَاتِ بِوُضُوءٍ وَاحِدٍ ثُمَّ سَأَلْتُهُ بَعْدُ فَقَالَ مَا لَمْ يُحْدِثْ
