"I saw 'Ali (may Allah be please with him) praying Zuhr, then he sat to tend to the people's needs, and when the time for 'Asr came, a vessel of water was brought to him. He took a handful of it and wiped his face, forearms, head and feet with it, then he took what was left and drank standing up. He said: 'People dislike this, but I saw the Messenger of Allah ﷺ doing it. This is the Wudu' of one who has not committed Hadath."  

رَأَيْتُ عَلِيًّا ؓ صَلَّى الظُّهْرَ ثُمَّ قَعَدَ لِحَوَائِجِ النَّاسِ فَلَمَّا حَضَرَتِ الْعَصْرُ أُتِيَ بِتَوْرٍ مِنْ مَاءٍ فَأَخَذَ مِنْهُ كَفًّا فَمَسَحَ بِهِ وَجْهَهُ وَذِرَاعَيْهِ وَرَأْسَهُ وَرِجْلَيْهِ ثُمَّ أَخَذَ فَضْلَهُ فَشَرِبَ قَائِمًا وَقَالَ إِنَّ نَاسًا يَكْرَهُونَ هَذَا وَقَدْ رَأَيْتُ رَسُولَ اللَّهِ ﷺ يَفْعَلُهُ وَهَذَا وُضُوءُ مَنْ لَمْ يُحْدِثْ
