Sunan an-Nasa'i 78
It was narrated that Anas said:
"Some of the Companions of the Prophet (ﷺ) were looking for (water for) Wudu'. The Messenger of Allah (ﷺ) said: 'Do any of you have water?' He put his hand in the water and said: 'Perform Wudu' in the Name of Allah.' I saw the water coming out from between his fingers until they had all performed Wudu'." Thabit said: "I said to Anas: 'How many did you see?' He said: 'About seventy.'"
أَخْبَرَنَا إِسْحَاقُ بْنُ إِبْرَاهِيمَ، قَالَ أَنْبَأَنَا عَبْدُ الرَّزَّاقِ، قَالَ حَدَّثَنَا مَعْمَرٌ، عَنْ ثَابِتٍ، وَقَتَادَةُ، عَنْ أَنَسٍ، قَالَ طَلَبَ بَعْضُ أَصْحَابِ النَّبِيِّ صلى الله عليه وسلم وَضُوءًا فَقَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم ‏"‏ هَلْ مَعَ أَحَدٍ مِنْكُمْ مَاءٌ ‏"‏ ‏.‏ فَوَضَعَ يَدَهُ فِي الْمَاءِ وَيَقُولُ ‏"‏ تَوَضَّئُوا بِسْمِ اللَّهِ ‏"‏ ‏.‏ فَرَأَيْتُ الْمَاءَ يَخْرُجُ مِنْ بَيْنِ أَصَابِعِهِ حَتَّى تَوَضَّئُوا مِنْ عِنْدِ آخِرِهِمْ ‏.‏ قَالَ ثَابِتٌ قُلْتُ لأَنَسٍ كَمْ تُرَاهُمْ قَالَ نَحْوًا مِنْ سَبْعِينَ ‏.‏
