After tauheed and risaalat (the oneness of Allah Ta‘ala and being blessed with prophethood), the very first thing which Rasulullah (sallallahu ‘alaihi wasallam) was taught was wudhu and salaah.

Hazrat Jibraa’eel (‘alaihis salaam) commenced by stamping his heel on the ground, causing a spring to flow. Hazrat Jibraa’eel (‘alaihis salaam) then performed wudhu with this water while Rasulullah (sallallahu ‘alaihi wasallam) observed his actions. Rasulullah (sallallahu ‘alaihi wasallam) then also performed wudhu accordingly. Thereafter, Hazrat Jibraa’eel (‘alaihis salaam) performed two rakaats of salaah with Rasulullah (sallallahu ‘alaihi wasallam) following him in the salaah. After learning to perform wudhu and salaah, Rasulullah (sallallahu ‘alaihi wasallam) returned home and taught Hazrat Khadijah (radhiyallahu ‘anha) how to perform wudhu and salaah.
