O you who believe! do not go near prayer when you are Intoxicated until you know (well) what you say, nor when you are under an obligation to perform a bath-- unless (you are) travelling on the road-- until you have washed yourselves; and if you are sick, or on a journey, or one of you come from the privy or you have touched the women, and you cannot find water, betake yourselves to pure earth, then wipe your faces and your hands; surely Allah is Pardoning, Forgiving.

And when he came to the water of Madyan, he found on it a group of men watering, and he found besides them two women keeping back (their flocks). He said: What is the matter with you? They said: We cannot water until the shepherds take away (their sheep) from the water, and our father is a very old man.
