According to search-discovered classical Islamic scholarship, Wudu (Ablution) is a mandatory act of ritual purification detailed in Surah Al-Ma'idah (5:6) of the Quran. Classical exegetes like Ibn Kathir and Al-Qurtubi explain that this verse establishes the four obligatory (Fard) components: washing the face and arms to the elbows, wiping the head, and washing the feet to the ankles. Linguistically derived from a root meaning 'brightness' and 'beauty', Wudu is more than physical cleansing; it is a spiritual preparation for worship. The Sunnah of the Prophet Muhammad (ﷺ) provides further details on recommended acts, such as rinsing the mouth and nose, which enhance the ritual. Fiqh (Islamic jurisprudence) clarifies that Wudu is a prerequisite for valid Salah (prayer) and other specific acts of worship, serving to remove a state of minor ritual impurity and, as numerous hadiths confirm, to spiritually cleanse a believer from their minor sins.
