Ghusl is a ritual purification in Islam that involves a full-body wash. It is required in specific situations, such as after sexual activity, menstruation, or childbirth. The purpose of Ghusl is to achieve spiritual cleanliness and prepare for prayer and other acts of worship. The process of Ghusl includes several steps: intending to purify oneself, washing the hands, rinsing the mouth and nostrils, and then washing the entire body thoroughly. This practice emphasizes the importance of cleanliness in Islam and is a key aspect of maintaining spiritual and physical hygiene.
