A bowl of water was brought to the Prophet ﷺ while he was at Az-Zawra. He placed his hand in it and the water started flowing among his fingers. All the people performed ablution (with that water). Qatada asked Anas, "How many people were you?" Anas replied, "Three hundred or nearly three hundred."  

أُتِيَ النَّبِيُّ ﷺ بِإِنَاءٍ وَهْوَ بِالزَّوْرَاءِ فَوَضَعَ يَدَهُ فِي الإِنَاءِ فَجَعَلَ الْمَاءُ يَنْبُعُ مِنْ بَيْنِ أَصَابِعِهِ فَتَوَضَّأَ الْقَوْمُ قَالَ قَتَادَةُ قُلْتُ لأَنَسٍ كَمْ كُنْتُمْ قَالَ ثَلاَثَمِائَةٍ أَوْ زُهَاءَ ثَلاَثِمِائَةٍ  

[Machine] That the Prophet of Allah ﷺ was in al-Zawrāʾ. So, a container with water was brought to him, in which his fingers couldn't be completely submerged or could hardly be submerged. He commanded his companions to perform ablution. He then placed his hand in the water, and the water began to flow from between his fingers and the tips of his fingers until the people performed ablution. So, we asked Anas, "How many were you?" He said, "We were three hundred."  

أَنَّ نَبِيَّ اللهِ ﷺ كَانَ بِالزَّوْرَاءِ فَأُتِيَ بِإِنَاءٍ فِيهِ مَاءٌ لَا يَغْمُرُ أَصَابِعَهُ أو قدر ما يري أصابعه فَأَمَرَ أَصْحَابَهُ أَنْ يَتَوَضَّئُوا فَوَضَعَ كَفَّهُ فِي الْمَاءِ فَجَعَلَ الْمَاءُ يَنْبُعُ مِنْ بَيْنِ أَصَابِعِهِ وَأَطْرَافِ أَصَابِعِهِ حَتَّى تَوَضَّأَ الْقَوْمُ قَالَ فَقُلْنَا لِأَنَسٍ كَمْ كُنْتُمْ؟ قَالَ كُنَّا ثَلَاثَ مِائَةٍ
