Musnad Ahmad 1027
It was narrated that ‘Abd Khair said:
We prayed fajr then we went to him [‘Ali] and sat with him. He called for (water) for wudoo’ and a small vessel of water and a large vessel were brought. He emptied the small vessel into his right hand and washed his hands three times, rinsed his mouth three times and rinsed his nose three times, using one handful of water each time. Then he washed his face three times and his forearms three times each. Then he put his hand in the small vessel and wiped his head with both hands together once. Then he washed his feet three times each. Then he said: This is the wudoo` of your Prophet (ﷺ), so learn it
حَدَّثَنَا عَبْد اللَّهِ، حَدَّثَنَا مُحَمَّدُ بْنُ جَعْفَرٍ الْوَرَكَانِيُّ، أَنْبَأَنَا شَرِيكٌ، عَنْ خَالِدِ بْنِ عَلْقَمَةَ، عَنْ عَبْدِ خَيْرٍ، قَالَ صَلَّيْنَا الْغَدَاةَ فَأَتَيْنَاهُ فَجَلَسْنَا إِلَيْهِ فَدَعَا بِوَضُوءٍ فَأُتِيَ بِرَكْوَةٍ فِيهَا مَاءٌ وَطَسْتٍ قَالَ فَأَفْرَغَ الرَّكْوَةَ عَلَى يَدِهِ الْيُمْنَى فَغَسَلَ يَدَيْهِ ثَلَاثًا وَتَمَضْمَضَ ثَلَاثًا وَاسْتَنْثَرَ ثَلَاثًا بِكَفٍّ كَفٍّ ثُمَّ غَسَلَ وَجْهَهُ ثَلَاثًا وَذِرَاعَيْهِ ثَلَاثًا ثَلَاثًا ثُمَّ وَضَعَ يَدَهُ فِي الرَّكْوَةِ فَمَسَحَ بِهَا رَأْسَهُ بِكَفَّيْهِ جَمِيعًا مَرَّةً وَاحِدَةً ثُمَّ غَسَلَ رِجْلَيْهِ ثَقَابًا ثَلَاثًا ثُمَّ قَالَ هَذَا وُضُوءُ نَبِيِّكُمْ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ فَاعْلَمُوهُ‏.‏
