I saw ‘Ali ؓ doing wudooʿ. He washed his hands until they were clean, then he rinsed his mouth three times, then he rinsed his nose three times; he washed his face three times and his forearms three times; he wiped his head and washed his feet up to the ankles. And he took the leftover water and drank it whilst standing. Then he said: I wanted to show you how the Messenger of Allah ﷺ did wudooʿ ‘Abd Khair narrated a hadeeth like that of Abu Hayyah from ʿAli, except that ’Abd Khair said: When he finished his wudoo’, he took some of the leftover water in his hand and drank it. (Using translation from Aḥmad 1046)
رَأَيْتُ عَلِيًّا تَوَضَّأَ فَغَسَلَ كَفَّيْهِ حَتَّى أَنْقَاهُمَا ثُمَّ مَضْمَضَ ثَلَاثًا وَاسْتَنْشَقَ ثَلَاثًا وَغَسَلَ وَجْهَهُ ثَلَاثًا وَغَسَلَ ذِرَاعَيْهِ ثَلَاثًا ثُمَّ مَسَحَ بِرَأْسِهِ ثُمَّ غَسَلَ قَدَمَيْهِ إِلَى الْكَعْبَيْنِ ثُمَّ قَامَ فَأَخَذَ فَضْلَ طَهُورِهِ فَشَرِبَ وَهُو قَائِمٌ ثُمَّ قَالَ أَحْبَبْتُ أَنْ أُرِيَكُمْ كَيْفَ طُهُورُ النَّبِيِّ ﷺ
