O you who believe! Do not come forward to (stand in) the Prayer while you are in (any sort of) state of drunkenness until you know what you are saying, nor while you are in the state of ritual impurity (requiring the total ablution) – save when you are on a journey (and then unable to bathe) – until you have bathed (done the total ablution). But if you are ill, or on a journey, or if any of you has just satisfied a call of nature, or you have had contact with women, and can find no water, then betake yourselves to pure earth, passing with it lightly over your face and hands (and forearms up to and including the elbows). Assuredly God is One Who grants remission, All-Forgiving.
