Indeed there was a sign for you in the two hosts (which) met together in encounter; one party fighting in the way of Allah and the other unbelieving, whom they saw twice as many as themselves with the sight of the eye and Allah strengthens with His aid whom He pleases; most surely there is a lesson in this for those who have sight.

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.
