حَدَّثَنَا مُحَمَّدُ بْنُ بَشَّارٍ، حَدَّثَنَا يَحْيَى بْنُ سَعِيدٍ، وَعَبْدُ الرَّحْمَنِ، هُوَ ابْنُ مَهْدِيٍّ قَالاَ حَدَّثَنَا سُفْيَانُ بْنُ سَعِيدٍ، عَنْ عَمْرِو بْنِ عَامِرٍ الأَنْصَارِيِّ، قَالَ سَمِعْتُ أَنَسَ بْنَ مَالِكٍ، يَقُولُ كَانَ النَّبِيُّ صلى الله عليه وسلم يَتَوَضَّأُ عِنْدَ كُلِّ صَلاَةٍ . قُلْتُ فَأَنْتُمْ مَا كُنْتُمْ تَصْنَعُونَ قَالَ كُنَّا نُصَلِّي الصَّلَوَاتِ كُلَّهَا بِوُضُوءٍ وَاحِدٍ مَا لَمْ نُحْدِثْ . قَالَ أَبُو عِيسَى هَذَا حَدِيثٌ حَسَنٌ صَحِيحٌ .
Amr bin Amir Al-Ansari narrated that he heard Anas bin Malik saying: "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)." Translation Not Available
