In Islam, ablution, or Wudhoo', is to wash one’s face, hands, arms, head and feet with water. Allah, the Most High, Says (what means): “O you who have believed! When you rise to [perform] prayer, wash your faces and your forearms to the elbows and wipe over your heads and wash your feet to the ankles..." [Quran 5:6]

Abu Hurayrah may Allah be pleased with him, narrated that he Prophet said: “Allah does not accept the prayer of one who nullified his ablution until he performs it again.” [Al-Bukhari, Muslim, Abu Daawood and At-Tirmithi]

There are many reports describing the manner in which the Prophet performed ablution, and the following is one of them. Humraan, the freed slave of 'Uthmaan bin 'Affaan may Allah be pleased with him narrated that 'Uthmaan may Allah be pleased with him once asked for a tumbler of water in order to perform ablution; when it was brought to him, he poured water from it over his hands and washed them thrice, and then put his right hand in the water container and rinsed his mouth and washed his nose by putting water in it and then blowing it out. Then, he washed his face thrice and then his forearms up to the elbows thrice; then, he passed his wet hands over his head and then washed each foot thrice. After that, 'Uthmaan may Allah be pleased with him said: "I saw the Prophet perform ablution like this of mine, and he then said: "If anyone performs ablution like that of mine and offers a two-Rak'ah (units) prayer during which he does not think of anything else (not related to the present prayer) then his past sins will be forgiven." [Al-Bukhari]

(ii) Washing the arms to the elbows: The elbows must be washed, for the Prophet did so.

(iii) Wiping the head: This means to wipe one’s head with wet hands. The apparent meaning of the Quranic words (which mean): “… and wipe over your heads…” [Quran 5:6] does not imply that all of the head needs to be wiped yet the way of the prophet is what confirms this fact. Three different ways were recorded of how he would wipe his head:

(a) Wiping all of his head: ‘Abdullaah Ibn Zayd may Allah be pleased with him reported that the Prophet would wipe his entire head with his hands. He would start with the front of his head, then move to the back, and then return his hands to the front. [Ibn Maajah, Abu Daawood and others']

(b) Wiping over the turban only: Bilaal may Allah be pleased with him reported that the Prophet said: “Wipe over your shoes and head covering.” [Ahmad]. It should be noted that the condition for wiping over the turban and socks is that prior ablution was performed before putting them on. Many Prophetic narrations have been related on this topic by Imaams Al-Bukhari, Muslim and others .

(c) Wiping over the front portion of the scalp and the turban: Al-Mugheerah Ibn Shu’bah may Allah be pleased with him stated: "The Messenger of Allah performed ablution and wiped over the front portion of his scalp, his turban and his socks." [Muslim]

There is, however, no strong Prophetic narration that clearly states that he wiped over part of his head, even though the verse [Quran: 5:6] apparently implies it. It is also not sufficient just to wipe over locks of hair that proceed from the head or along the sides of the head.

(iv) Washing the feet and the heels: This has been confirmed in narrations from the Prophet concerning his actions and statements. Ibn ‘Umar may Allah be pleased with him said warning against not properly and entirely washing the feet: “(Once), the Prophet lagged behind us on one of our journeys. He caught up with us after we had delayed the afternoon prayer. We started to make ablution and were (only) wiping over our feet (and not washing them) when he said: “Woe to these heels! Save them from the Hell-fire" repeating it twice or thrice.” [Al-Bukhari and Muslim]

The following acts are not obligatory, yet, once done, are rewarded for since they constitute the way the Prophet used to perform ablution:
