Musnad Ahmad 970
It was narrated from ‘Ali (رضي الله عنه) that He called for a jug of water, then he said:
Where are those who say that they dislike drinking whilst standing? He took it and drank whilst standing then he did a light wudoo` and wiped over his shoes, then he said: This is the wudoo’ of the Messenger of Allah (ﷺ) for one who is pure and has not broken his wudoo’.
حَدَّثَنَا ابْنُ الْأَشْجَعِيِّ، حَدَّثَنَا أَبِي، عَنْ سُفْيَانَ، عَنِ السُّدِّيِّ، عَنْ عَبْدِ خَيْرٍ، عَنْ عَلِيٍّ، رَضِيَ اللَّهُ عَنْهُ أَنَّهُ دَعَا بِكُوزٍ مِنْ مَاءٍ ثُمَّ قَالَ أَيْنَ هَؤُلَاءِ الَّذِينَ يَزْعُمُونَ أَنَّهُمْ يَكْرَهُونَ الشُّرْبَ قَائِمًا قَالَ فَأَخَذَهُ فَشَرِبَ وَهُوَ قَائِمٌ ثُمَّ تَوَضَّأَ وُضُوءًا خَفِيفًا وَمَسَحَ عَلَى نَعْلَيْهِ ثُمَّ قَالَ هَكَذَا وُضُوءُ رَسُولِ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ لِلطَّاهِرِ مَا لَمْ يُحْدِثْ‏.‏
