Wudu

Wudu (ওজু / Al-Wudu’ / الوُضُوء) in Tibb an-Nabawi & Modern Health Science

Wudu (Arabic: الوُضُوء—Al-Wudu’; Bengali: ওজু / ওজু করা; English: Ritual Ablution) is the prescribed Islamic act of ritual purification performed using clean water before acts of worship, such as Salah. Beyond its spiritual purpose as a requirement for ritual purity (Taharah), Wudu serves as a comprehensive daily personal hygiene routine that promotes neurological, dermatological, and circulatory health.

Traditional & Classical Islamic Perspective

Constant State of Purity (Taharah): The Prophet Muhammad (ﷺ) emphasized maintaining Wudu throughout the day, describing it as a spiritual shield and a source of radiant light (Nur) on the Day of Resurrection.

Hydrotherapy & Temperature Regulation: Classical medical scholars noted that washing the extremities (hands, mouth, nose, face, arms, head, and feet) with cool water washes away external impurities, cools bodily heat, and calms emotional agitation or anger.

Circadian Hygiene Routine: Performing Wudu up to five times daily ensures that the areas of the body most exposed to environmental pollutants, microbes, and allergens are regularly cleansed.
