And they ask you about menstruation. Say: It is a discomfort; therefore keep aloof from the women during the menstrual discharge and do not go near them until they have become clean; then when they have cleansed themselves, go in to them as Allah has commanded you; surely Allah loves those who turn much (to Him), and He loves those who purify themselves.

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.
