Musnad Ahmad 1198
It was narrated that ‘Abd Khair said. We Prayed Fajr, then we sat with ‘Ali bin Abi Talib (رضي الله عنه). He called for water for wudoo’, then he washed his hands three times, rinsed his mouth twice from one handful, then he washed his face three times, then he washed his forearms, then he washed his feet three times. Then he said:
This is the wudoo’ of your Prophet (ﷺ), so learn it.
حَدَّثَنَا عَبْد اللَّهِ، حَدَّثَنَا زَكَرِيَّا بْنُ يَحْيَى، رَحْمَوَيْهِ حَدَّثَنَا شَرِيكٌ، عَنْ خَالِدِ بْنِ عَلْقَمَةَ، عَنْ عَبْدِ خَيْرٍ، قَالَ صَلَّيْنَا الْغَدَاةَ فَجَلَسْنَا إِلَى عَلِيِّ بْنِ أَبِي طَالِبٍ رَضِيَ اللَّهُ عَنْهُ فَدَعَا بِوَضُوءٍ فَغَسَلَ يَدَيْهِ ثَلَاثًا وَمَضْمَضَ مَرَّتَيْنِ مِنْ كَفٍّ وَاحِدٍ ثُمَّ غَسَلَ وَجْهَهُ ثَلَاثًا ثُمَّ غَسَلَ ذِرَاعَيْهِ ثُمَّ غَسَلَ قَدَمَيْهِ ثَلَاثًا ثُمَّ قَالَ هَذَا وُضُوءُ نَبِيِّكُمْ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ فَاعْلَمُوا‏.‏
