Musnad Ahmad 1005
It was narrated from an-Nazzal bin Sabrah that When ‘Ali (رضي الله عنه) prayed Zuhr, he called for a vessel of water in ar-Rahbah and drank whilst standing. Then he said:
Some men dislike this, but I saw the Messenger of Allah (ﷺ) do what you have seen me do. Then he wiped himself with what was left over and said: This is the wudoo’ of one who has not broken his wudoo’.
حَدَّثَنَا وَكِيعٌ، حَدَّثَنِي شُعْبَةُ، عَنْ عَبْدِ الْمَلِكِ بْنِ مَيْسَرَةَ، عَنِ النَّزَّالِ بْنِ سَبْرَةَ، أَنَّ عَلِيًّا، رَضِيَ اللَّهُ عَنْهُ لَمَّا صَلَّى الظُّهْرَ دَعَا بِكُوزٍ مِنْ مَاءٍ فِي الرَّحَبَةِ فَشَرِبَ وَهُوَ قَائِمٌ ثُمَّ قَالَ إِنَّ رِجَالًا يَكْرَهُونَ هَذَا وَإِنِّي رَأَيْتُ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ فَعَلَ كَالَّذِي رَأَيْتُمُونِي فَعَلْتُ ثُمَّ تَمَسَّحَ بِفَضْلِهِ وَقَالَ هَذَا وُضُوءُ مَنْ لَمْ يُحْدِثْ‏.‏
