حَدَّثَنَا هَنَّادٌ، وَقُتَيْبَةُ، قَالاَ حَدَّثَنَا أَبُو الأَحْوَصِ، عَنْ أَبِي إِسْحَاقَ، عَنْ أَبِي حَيَّةَ، قَالَ رَأَيْتُ عَلِيًّا تَوَضَّأَ فَغَسَلَ كَفَّيْهِ حَتَّى أَنْقَاهُمَا ثُمَّ مَضْمَضَ ثَلاَثًا وَاسْتَنْشَقَ ثَلاَثًا وَغَسَلَ وَجْهَهُ ثَلاَثًا وَذِرَاعَيْهِ ثَلاَثًا وَمَسَحَ بِرَأْسِهِ مَرَّةً ثُمَّ غَسَلَ قَدَمَيْهِ إِلَى الْكَعْبَيْنِ ثُمَّ قَامَ فَأَخَذَ فَضْلَ طَهُورِهِ فَشَرِبَهُ وَهُوَ قَائِمٌ ثُمَّ قَالَ أَحْبَبْتُ أَنْ أُرِيَكُمْ كَيْفَ كَانَ طُهُورُ رَسُولِ اللَّهِ صلى الله عليه وسلم . قَالَ أَبُو عِيسَى وَفِي الْبَابِ عَنْ عُثْمَانَ وَعَبْدِ اللَّهِ بْنِ زَيْدٍ وَابْنِ عَبَّاسٍ وَعَبْدِ اللَّهِ بْنِ عَمْرٍو وَالرُّبَيِّعِ وَعَبْدِ اللَّهِ بْنِ أُنَيْسٍ وَعَائِشَةَ رِضْوَانُ اللَّهِ عَلَيْهِمْ .
Abu Hayyah narrated:
"I saw Ali performing Wudu. He washed his hands until he cleaned them, then he rinsed out his mouth three times, sniffed water into his nose and blew it out three times, washed his face three times, and his forearms three times. He wiped his head once, then he washed his feet up to the ankles. Then he stood up, taking what was left over from his purification (water) and drank it while he was standing. Then he said, 'I wanted to show you how Allah's Messenger purified himself.'"
