This hadith explains how one should perform wudoo', which is an Islamic ritual that involves washing certain parts of one's body with water. It was narrated by Abd Khair who said that they prayed fajr then went to Ali who called for water for wudoo'. A small vessel and a large vessel were brought, from which Ali emptied some water into his right hand before washing each part three times - hands, mouth, nose, face and forearms - using one handful of water each time. After this he put his hand in the small vessel again before wiping over head with both hands together once. Finally he washed feet three times each before saying that this was how their prophet performed wudoo', so they should learn it too. This hadith teaches us about cleanliness as well as following in our prophet's footsteps when performing religious rituals such as prayer or ablution.
