Purification (tahara) opens the whole fiqh of worship: Ibn Qudama's definition, its obligatory status by the Book, the Sunna and consensus, and the ruling on prayer made without purification.

Purification (tahara) is the gateway act of worship: it removes whatever prevents prayer, whether minor or major ritual impurity, or material filth. It is the first door of worship in Islam and a condition of validity for every prayer.
Ibn Qudama (may Allah have mercy on him) defined it as: "removing what prevents prayer, whether a state of impurity (hadath) or filth, by means of water, or removing its ruling by means of dust" (al-Mughni with its commentary 1/29; Kashshaf al-Qina 1/24).
Purification is obligatory by the Book, the Sunna and consensus, and it is a condition of the prayer's validity: the prayer, whether obligatory or supererogatory, is not valid without it.
The Book first. Allah the Most High says:
"O you who believe, when you rise for prayer, wash your faces and your hands up to the elbows, wipe your heads and your feet up to the ankles."
Surah al-Ma'ida, 6
And He says:
"O you who believe, do not approach prayer while intoxicated, until you know what you are saying, nor in a state of major impurity, except when passing through, until you have washed yourselves."
Surah an-Nisa, 43
The Sunna next: the many reports from the Messenger of Allah (peace and blessings of Allah be upon him) establish the obligation of purification for prayer and that it is a condition of its validity. He said, among other things:
Allah does not accept a prayer without purification.Muslim 224
An-Nawawi said: "This hadith is an explicit text on the obligation of purification for prayer" (Sharh Sahih Muslim 3/84).
Ibn al-Mundhir (may Allah have mercy on him) said: "The people of knowledge are unanimous that prayer is only valid with purification, when one has the means for it" (al-Ijma 19; al-Awsat 1/109; also transmitted by Ibn Hubayra in al-Ifsah 1/35). An-Nawawi said: "The community has agreed that purification is a condition of the prayer's validity."
Al-Qadi Iyad reported a disagreement over when purification was made obligatory: Ibn Jahm held that ablution was first recommended at the beginning of Islam, then its obligation came down with the verse of tayammum; the majority answered that the obligation preceded that. They also disagreed on whether ablution is obligatory for every prayer or only for one in a state of impurity: some early scholars made it obligatory for every prayer, relying on Allah's words "when you rise for prayer"; others held that this obligation existed and was then abrogated; still others that it is simply recommended for each prayer. After discussion, the people of knowledge settled on the last sense: the obligation falls only on the one who incurs impurity, but renewing ablution for every prayer remains recommended.
The community agreed on the prohibition of praying without purification, by water or dust, with no distinction between the obligatory and the supererogatory prayer, the prostration of recitation, the prostration of gratitude or the funeral prayer. It is only reported from ash-Sha'bi and Muhammad ibn Jarir at-Tabari that they allowed the funeral prayer without purification: a rejected view, the scholars being unanimous against it.
As for one who deliberately prayed in a state of impurity with no excuse, he sins without becoming an apostate, according to our school and the majority of scholars. It is reported from Abu Hanifa (may Allah have mercy on him) that he held him an apostate, by way of mockery; but the rule is that apostasy lies in belief, and this worshiper's belief remains sound. All of this applies when the worshiper has no excuse for his state (Sharh Sahih Muslim 3/102-103).
