Wuḍhu (Arabic: الوضوء al-wuḍū, Persian: آبدست ābdast, Urdu: وضو vazū, Turkish: abdest, Pashto: awdas, Bengali: ojoo, Indonesian: wudhu, Chechen: Lamaz etsar, Bosnian: abdest, Kurdish: destnivêj, Somali: weeso) is the Islamic procedure for washing parts of the body using water often in preparation for formal prayers (salah). The Qur'an says "For Allah loves those who turn to Him constantly and He loves those who keep themselves pure and clean."

Muslims are also required to be clean when handling and reading the Qur'an. The Qur'an says "Which none shall touch but those who are clean." Purification of the body and clothes is called taharah. The Islamic prophet Muhammad said that "Cleanliness is half of faith". To have taharah for the body, one should do either ghusl or wudu. Wudu is often translated as "partial ablution", as opposed to ghusl, or "full ablution".

Muslims often recite the Durood and Ayatul Kursi after ablution^{[citation needed]}

There are four fard (obligatory) acts. If one of these acts is omitted, it must be returned to and then completion of the successive acts are to be performed.
