Water is considered a purifier in most religions.
Faiths that incorporate ritual washing (ablution) include Christianity, Hinduism, Islam, Judaism, the Rastafari movement, Shinto, Taoism, and Wicca.
Immersion (or aspersion or affusion) of a person in water is a central sacrament of Christianity (where it is called baptism); it is also a part of the practice of other religions, including Islam (Ghusl), Judaism (mikvah) and Sikhism (Amrit Sanskar).
In addition, a ritual bath in pure water is performed for the dead in many religions including Islam and Judaism.
In Islam, the five daily prayers can be done in most cases after completing washing certain parts of the body using clean water (wudu), unless water is unavailable (see Tayammum).
In Shinto, water is used in almost all rituals to cleanse a person or an area (e.g., in the ritual of misogi).

In Christianity, holy water is water that has been sanctified by a priest for the purpose of baptism, the blessing of persons, places, and objects, or as a means of repelling evil.

In Zoroastrianism, water (āb) is respected as the source of life.
