Anas said that when God’s messenger performed ablution he took a handful of water, and putting it under his chin, made it go through his beard, saying, “Thus did my Lord command me.”
Laqit b. Sabira said that he asked God's messenger to tell him about ablution and he replied, “Perform ablution completely, let the water run between the fingers and toes,* and snuff up water freely unless you are fasting!’
*In the text only asabi’ is used, but this word is used for either fingers or toes, and on the analogy of the following traditions I have translated it as above. There it says “the asabi’ of your hands and your feet".
Abu Dawud, Tirmidhi and Nasa’i transmitted it, and Ibn Majah and Darimi transmitted it up to “between the fingers and toes”.
