Taharah (Purification): Wudu, Ghusl, and Tayammum

Taharah, or ritual purity, is the gateway to Islamic worship. The Prophet Muhammad, peace be upon him, said: "Cleanliness is half of faith" (Muslim). Without ritual purity, the prayer is invalid, and the Quran may not be handled. Islamic purification is both physical and spiritual — it disciplines the believer to approach God in a state of preparation and mindfulness.

Wudu (ablution) is the minor purification required before each prayer. The Quran commands it directly: "O you who believe, when you rise to perform prayer, wash your faces and your hands up to the elbows, and wipe your heads and wash your feet up to the ankles" (5:6). The obligatory acts of wudu are washing the face once, washing the hands and forearms up to and including the elbows, wiping the head, and washing the feet up to and including the ankles. Scholars agree on these four based on the Quranic verse. The Sunnah adds further recommended acts: beginning with the intention (niyyah), saying Bismillah, washing the hands before beginning, rinsing the mouth and nostrils, and repeating each washing up to three times.

Wudu is invalidated by passing wind, urinating, defecating, deep sleep, touching the private parts (according to some scholars), or the emission of pre-seminal fluid. When wudu breaks, a new ablution must be performed before prayer.

Ghusl (full body purification) is the major ablution required after sexual intercourse, ejaculation, the completion of menstruation, post-natal bleeding, and upon embracing Islam. The Quran states: "If you are in a state of janabah (major ritual impurity), then purify yourselves" (5:6). The minimum requirement for a valid ghusl is the intention, rinsing the mouth, clearing the nostrils, and washing the entire body — including the hair roots — with water reaching every part of the skin. The Sunnah method involves a more elaborate sequence beginning with washing the hands, removing any filth, performing wudu, and then pouring water over the entire body three times.

Tayammum is dry purification using clean earth or dust, permitted when water is unavailable or when using water would cause harm due to illness or extreme cold. Allah says: "And if you are ill or on a journey or one of you comes from the place of relieving himself or you have contacted women and find no water, then seek clean earth and wipe over your faces and hands" (5:6). Tayammum requires striking clean earth with both palms once, wiping the face, then wiping the hands. It performs the same legal function as wudu or ghusl and is invalidated by the same nullifiers, and additionally by the availability of water.

Sayyid Sabiq presents these rulings with careful attention to the hadith evidence, noting where scholars differ — such as whether wiping over socks (masah al-khuffayn) requires the socks to be worn from a state of purity, and for how long the wiping remains valid. The rules of purification reflect Islam's holistic view: bodily cleanliness, deliberate intention, and spiritual readiness together constitute the state in which a Muslim meets their Lord.
