'Abdullah b. Zaid b. 'Asim al-Ansari, who was a Companion (of the Prophet), reported:
It was said to him (by people): Perform for us the ablution (as it was performed) by the Messenger of Allah (ﷺ). He ('Abdullah b. Zaid) called for a vessel (of water), and poured water from it on his hands and washed them three times. Then he inserted his hand (in the vessel) and brought it (water) out, rinsed his mouth and snuffed up water from the palm of one hand doing that three times, He again inserted his hand and brought it out and washed his face three times, then inserted his hand and brought it out and washed each arm up to the elbow twice, then inserted his hand and brought it out and wiped his head both front and back with his hands. He then washed his feet up to the ankles, and then said: This is how God's Messenger (peace be upon him) performed ablution.
حَدَّثَنِي مُحَمَّدُ بْنُ الصَّبَّاحِ، حَدَّثَنَا خَالِدُ بْنُ عَبْدِ اللَّهِ، عَنْ عَمْرِو بْنِ يَحْيَى بْنِ عُمَارَةَ، عَنْ أَبِيهِ، عَنْ عَبْدِ اللَّهِ بْنِ زَيْدِ بْنِ عَاصِمٍ الأَنْصَارِيِّ، - وَكَانَتْ لَهُ صُحْبَةٌ - قَالَ قِيلَ لَهُ تَوَضَّأْ لَنَا وُضُوءَ رَسُولِ اللَّهِ صلى الله عليه وسلم . فَدَعَا بِإِنَاءٍ فَأَكْفَأَ مِنْهَا عَلَى يَدَيْهِ فَغَسَلَهُمَا ثَلاَثًا ثُمَّ أَدْخَلَ يَدَهُ فَاسْتَخْرَجَهَا فَمَضْمَضَ وَاسْتَنْشَقَ مِنْ كَفٍّ وَاحِدَةٍ فَفَعَلَ ذَلِكَ ثَلاَثًا ثُمَّ أَدْخَلَ يَدَهُ فَاسْتَخْرَجَهَا فَغَسَلَ وَجْهَهُ ثَلاَثًا ثُمَّ أَدْخَلَ يَدَهُ فَاسْتَخْرَجَهَا فَغَسَلَ يَدَيْهِ إِلَى الْمِرْفَقَيْنِ مَرَّتَيْنِ مَرَّتَيْنِ ثُمَّ أَدْخَلَ يَدَهُ فَاسْتَخْرَجَهَا فَمَسَحَ بِرَأْسِهِ فَأَقْبَلَ بِيَدَيْهِ وَأَدْبَرَ ثُمَّ غَسَلَ رِجْلَيْهِ إِلَى الْكَعْبَيْنِ ثُمَّ قَالَ هَكَذَا كَانَ وُضُوءُ رَسُولِ اللَّهِ صلى الله عليه وسلم .
