"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 ibn Malik saying that the Prophet ﷺ was brought a cup of water, and he performed ablution. So I said to Anas, "Was the Prophet ﷺ performing ablution before every prayer?" He said, "Yes." I asked, "What about you all?" He said, "We used to pray the prayers with one ablution." Then I asked him again, and he said, "We did not perform ablution unless we invalidated it."  

سَمِعْتُ أَنَسَ بْنَ مَالِكٍ يَقُولُ أُتِيَ النَّبِيُّ ﷺ بِقَدَحٍ مِنْ مَاءٍ فَتَوَضَّأَ قَالَ فَقُلْتُ لِأَنَسٍ أَكَانَ النَّبِيُّ ﷺ يَتَوَضَّأُ عِنْدَ كُلِّ صَلَاةٍ؟ قَالَ نَعَمْ قَالَ قُلْتُ فَأَنْتُمْ؟ قَالَ كُنَّا نُصَلِّي الصَّلَوَاتِ بِوُضُوءٍ وَاحِدٍ قَالَ ثُمَّ سَأَلْتُهُ بَعْدَ ذَلِكَ فَقَالَ مَا لَمْ نُحْدِثْ
