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 if We had sent to you a writing on a paper, then they had touched it with their hands, certainly those who disbelieve would have said: This is nothing but clear enchantment.

On the day when the hypocritical men and the hypocritical women will say to those who believe: Wait for us, that we may have light from your light; it shall be said: Turn back and seek a light. Then separation would be brought about between them, with a wall having a door in it; (as for) the inside of it, there shall be mercy in it, and (as for) the outside of it, before it there shall be punishment.
