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 it is said to them, Come to what Allah has revealed and to the Messenger, they say: That on which we found our fathers is sufficient for us. What! even though their fathers knew nothing and did not follow the right way.

And when they commit an indecency they say: We found our fathers doing this, and Allah has enjoined it on us. Say: Surely Allah does not enjoin indecency; do you say against Allah what you do not know?

But if you do not find any one therein, then do not enter them until permission is given to you; and if it is said to you: Go back, then go back; this is purer for you; and Allah is Cognizant of what you do.
