Sahn is a word that is used in the Islamic religion to describe a special way of washing your hands, mouth, nose, face, arms, head, and feet before you pray. It is a very important part of the Islamic faith because it helps people cleanse their bodies and their souls before communicating with God through prayer. When you perform sahn, you have to use clean water and make sure that you wash each part of your body in a special way that has been described in Islamic teachings. This way, you can show respect and devotion to God and prepare yourself to pray with a pure heart and mind.
