Sunan Abi Dawud 126
Narrated Ar-Rubayyi' daughter of Mu'awwidh ibn Afra':
The Messenger of Allah (ﷺ) used to come to us. He once said: Pour ablution water on me. She then described how the Prophet (ﷺ) performed ablution saying: He washed his hands up to wrist three times and washed his face three times, and rinsed his mouth and snuffed up water once.  Then he washed his forearms three times and wiped his head twice beginning from the back of his head, then wiped its front. He wiped his ears outside and inside. Then he washed his feet three times.
حَدَّثَنَا مُسَدَّدٌ، حَدَّثَنَا بِشْرُ بْنُ الْمُفَضَّلِ، حَدَّثَنَا عَبْدُ اللَّهِ بْنُ مُحَمَّدِ بْنِ عَقِيلٍ، عَنِ الرُّبَيِّعِ بِنْتِ مُعَوِّذِ ابْنِ عَفْرَاءَ، قَالَتْ كَانَ رَسُولُ اللَّهِ صلى الله عليه وسلم يَأْتِينَا فَحَدَّثَتْنَا أَنَّهُ قَالَ ‏
"‏ اسْكُبِي لِي وَضُوءًا ‏"‏ ‏.‏ فَذَكَرَتْ وُضُوءَ رَسُولِ اللَّهِ صلى الله عليه وسلم قَالَتْ فِيهِ فَغَسَلَ كَفَّيْهِ ثَلاَثًا وَوَضَّأَ وَجْهَهُ ثَلاَثًا وَمَضْمَضَ وَاسْتَنْشَقَ مَرَّةً وَوَضَّأَ يَدَيْهِ ثَلاَثًا ثَلاَثًا وَمَسَحَ بِرَأْسِهِ مَرَّتَيْنِ يَبْدَأُ بِمُؤَخَّرِ رَأْسِهِ ثُمَّ بِمُقَدَّمِهِ وَبِأُذُنَيْهِ كِلْتَيْهِمَا ظُهُورِهِمَا وَبُطُونِهِمَا وَوَضَّأَ رِجْلَيْهِ ثَلاَثًا ثَلاَثًا ‏.‏ قَالَ أَبُو دَاوُدَ وَهَذَا مَعْنَى حَدِيثِ مُسَدَّدٍ ‏.‏
