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.

Has not the account reached you of those before you, of the people of Nuh and Ad and Samood, and those after them? None knows them but Allah. Their messengers come to them with clear arguments, but they thrust their hands into their mouths and said: Surely we deny that with which you are sent, and most surely we are in serious doubt as to that to which you invite us.
