Sahih al-Bukhari 169Book 4, Hadith 35
حَدَّثَنَا عَبْدُ اللَّهِ بْنُ يُوسُفَ، قَالَ أَخْبَرَنَا مَالِكٌ، عَنْ إِسْحَاقَ بْنِ عَبْدِ اللَّهِ بْنِ أَبِي طَلْحَةَ، عَنْ أَنَسِ بْنِ مَالِكٍ، أَنَّهُ قَالَ رَأَيْتُ رَسُولَ اللَّهِ صلى الله عليه وسلم وَحَانَتْ صَلاَةُ الْعَصْرِ، فَالْتَمَسَ النَّاسُ الْوَضُوءَ فَلَمْ يَجِدُوهُ، فَأُتِيَ رَسُولُ اللَّهِ صلى الله عليه وسلم بِوَضُوءٍ، فَوَضَعَ رَسُولُ اللَّهِ صلى الله عليه وسلم فِي ذَلِكَ الإِنَاءِ يَدَهُ، وَأَمَرَ النَّاسَ أَنْ يَتَوَضَّئُوا مِنْهُ. قَالَ فَرَأَيْتُ الْمَاءَ يَنْبُعُ مِنْ تَحْتِ أَصَابِعِهِ حَتَّى تَوَضَّئُوا مِنْ عِنْدِ آخِرِهِمْ.
saw Allah's Messenger (ﷺ) when the `Asr prayer was due and the people searched for water to perform ablution but they could not find it. Later on (a pot full of) water for ablution was brought to Allah's Apostle . He put his hand in that pot and ordered the people to perform ablution from it. I saw the water springing out from underneath his fingers till all of them performed the ablution (it was one of the miracles of the Prophet).
