Sahih Bukhari Volume 1, Book 4, Hadith 191

حَدَّثَنَا مُسَدَّدٌ، قَالَ حَدَّثَنَا خَالِدُ بْنُ عَبْدِ اللَّهِ، قَالَ حَدَّثَنَا عَمْرُو بْنُ يَحْيَى، عَنْ أَبِيهِ، عَنْ عَبْدِ اللَّهِ بْنِ زَيْدٍ، أَنَّهُ أَفْرَغَ مِنَ الإِنَاءِ عَلَى يَدَيْهِ فَغَسَلَهُمَا، ثُمَّ غَسَلَ أَوْ مَضْمَضَ، وَاسْتَنْشَقَ مِنْ كَفَّةٍ وَاحِدَةٍ، فَفَعَلَ ذَلِكَ ثَلاَثًا، فَغَسَلَ يَدَيْهِ إِلَى الْمِرْفَقَيْنِ مَرَّتَيْنِ مَرَّتَيْنِ، وَمَسَحَ بِرَأْسِهِ مَا أَقْبَلَ وَمَا أَدْبَرَ، وَغَسَلَ رِجْلَيْهِ إِلَى الْكَعْبَيْنِ، ثُمَّ قَالَ هَكَذَا وُضُوءُ رَسُولِ اللَّهِ صلى الله عليه وسلم

Narrated By 'Amr bin Yahya : (On the authority of his father) 'Abdullah bin Zaid poured water on his hands from a utensil containing water and washed them and then with one handful of water he rinsed his mouth and cleaned his nose by putting water in it and then blowing it out. He repeated it thrice. He, then, washed his hands and forearms up to the elbows twice and passed wet hands over his head, both forwards and backwards, and washed his feet up to the ankles and said, "This is the ablution of Allah's Apostle."
