Wudu - Islamic procedure for washing parts of the body using water before formal prayers

"Wuḍūʾ is the Islamic procedure for cleansing parts of the body, a type of ritual purification, or ablution. Wudu consists of washing the face, arms, then wiping the head and finally washing the feet with water and is an important part of ritual purity in Islam. What activities require wuḍūʾ, what rituals constitute it and what breaks or invalidates it are governed by fiqh and specifically its rules concerning hygiene. - Wikipedia"
