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.

Zakir Abdul Karim Naik (Urdu: ذاکر عبدالکریم نائیک; born 18 October 1965) is an Indian public speaker on the subject of Islam and comparative religion. He is the founder and president of the Islamic Research Foundation (IRF), a non-profit organisation that owns the Peace TV channel based in Dubai, UAE. He is sometimes referred to as a televangelist. Before becoming a public speaker, he trained as a doctor. He has written two booklets on Islam and comparative religion. He is regarded as an exponent of the Salafi ideology; he places a strong emphasis on individual scholarship and the rejection of "blind Taqlid", which has led him to repudiate the relevance of sectarian or Madh'hab designations, all the while reaffirming their importance.
