It was narrated from 'Ali that: The Messenger of Allah performed ablution and he rinsed his mouth three times, and sniffed water up into his nose three times from one handful.
The act of performing ablution also has many spiritual benefits such as purifying our hearts and minds from any negative thoughts or feelings, so that we can focus on worshipping Allah with sincerity and humility. Additionally, it serves as a reminder for us to stay away from any kind of impurity or sinfulness in our lives, so that we can live according to Allah’s commands and teachings.
