43. O you who have faith in Allah and follow His Messenger, do not pray when you are drunk, until you recover from your drunkenness, and can tell what you are saying. (This ruling was before alcohol was completely forbidden.) Do not pray when you are in a state of major ritual impurity, and do not enter the mosques when you are in that state, except in passing, until you have washed your body. If you have an illness and cannot use water because of it, or if you are travelling, or have answered the call of nature, or have had sexual relations with women, and you cannot find water, then find clean earth, and wipe your faces and hands with it. Allah pardons your shortcomings and is Forgiving to you.
