The practice of wudu teaches us discipline, humility, and respect for ourselves and others around us. It also encourages us to take care of our bodies in order to maintain good health both physically and spiritually. Furthermore, it serves as an act of worship that brings us closer to Allah SWT through prayerful remembrance throughout the day.
