It was narrated that an-Nazzal bin Sabrah said:

A vessel of water was brought to ‘Ali (رضي الله عنه) and he drank whilst standing, then he said: I have heard that some people dislike it if one of them drinks whilst standing. But I saw the Messenger of Allah (ﷺ) do what I have done. Then he took some of the water and wiped himself. Then he said. This is the wudoo` of one who has not broken his wudoo’.

حَدَّثَنَا يَزِيدُ، أَنْبَأَنَا مِسْعَرٌ، عَنْ عَبْدِ الْمَلِكِ بْنِ مَيْسَرَةَ، عَنِ النَّزَّالِ بْنِ سَبْرَةَ، قَالَ أُتِيَ عَلِيٌّ بِإِنَاءٍ مِنْ مَاءٍ فَشَرِبَ وَهُوَ قَائِمٌ ثُمَّ قَالَ إِنَّهُ بَلَغَنِي أَنَّ أَقْوَامًا يَكْرَهُونَ أَنْ يَشْرَبَ أَحَدُهُمْ وَهُوَ قَائِمٌ وَقَدْ رَأَيْتُ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ فَعَلَ مِثْلَ مَا فَعَلْتُ ثُمَّ أَخَذَ مِنْهُ فَتَمَسَّحَ ثُمَّ قَالَ هَذَا وُضُوءُ مَنْ لَمْ يُحْدِثْ‏.‏
