Yahya related to me from Malik from Ishaq ibn Abdullah ibn Abi Talha that Anas ibn Malik said, "I saw the Messenger of Allah ﷺ on one occasion when the asr prayer was at hand . Everyone was looking for water for wudu but no- one could find any. Then the Messenger of Allah ﷺ brought some water in a vessel . He put his hand into the vessel and then he told them all to do wudu from it." Anas added, "I saw water coming out from his fingers. Then all of them to the last man did wudu."
أَنَّهُ قَالَ رَأَيْتُ رَسُولَ اللَّهِ ﷺ وَحَانَتْ صَلاَةُ الْعَصْرِ فَالْتَمَسَ النَّاسُ وَضُوءًا فَلَمْ يَجِدُوهُ فَأُتِيَ رَسُولُ اللَّهِ ﷺ بِوَضُوءٍ فِي إِنَاءٍ فَوَضَعَ رَسُولُ اللَّهِ ﷺ فِي ذَلِكَ الإِنَاءِ يَدَهُ ثُمَّ أَمَرَ النَّاسَ يَتَوَضَّئُونَ مِنْهُ قَالَ أَنَسٌ فَرَأَيْتُ الْمَاءَ يَنْبُعُ مِنْ تَحْتِ أَصَابِعِهِ فَتَوَضَّأَ النَّاسُ حَتَّى تَوَضَّئُوا مِنْ عِنْدِ آخِرِهِمْ
