Number of times to wash the hands
أَخْبَرَنَا قُتَيْبَةُ بْنُ سَعِيدٍ، قَالَ حَدَّثَنَا أَبُو الأَحْوَصِ، عَنْ أَبِي إِسْحَاقَ، عَنْ أَبِي حَيَّةَ، - وَهُوَ ابْنُ قَيْسٍ - قَالَ رَأَيْتُ عَلِيًّا - رضى الله عنه - تَوَضَّأَ فَغَسَلَ كَفَّيْهِ حَتَّى أَنْقَاهُمَا ثُمَّ تَمَضْمَضَ ثَلاَثًا وَاسْتَنْشَقَ ثَلاَثًا وَغَسَلَ وَجْهَهُ ثَلاَثًا وَغَسَلَ ذِرَاعَيْهِ ثَلاَثًا ثَلاَثًا ثُمَّ مَسَحَ بِرَأْسِهِ ثُمَّ غَسَلَ قَدَمَيْهِ إِلَى الْكَعْبَيْنِ ثُمَّ قَامَ فَأَخَذَ فَضْلَ طَهُورِهِ فَشَرِبَ وَهُوَ قَائِمٌ ثُمَّ قَالَ أَحْبَبْتُ أَنْ أُرِيَكُمْ كَيْفَ طَهُورُ النَّبِيِّ صلى الله عليه وسلم .
It was narrated that Abu Hayyah - Ibn Qais - said: "I saw 'Ali perform Wudu'. He washed his hands until they looked clean, then he rinsed his mouth three times and his nose three times, and he washed each forearm three times. Then he wiped his head, then he washed his feet up to the ankles. Then he stood up, took the left over water for his Wudu' and drank from it while standing. Then he said: 'I wanted to show you how the Prophet (ﷺ) performed Wudu'.'"
