O believers , draw not near to prayer when you are drunken until you know what you are saying , or defiled -- unless you are traversing a way -- until you have washed yourselves ; but if you are sick , or on a journey , or if any of you comes from the privy , or you have touched women , and you can find no water , then have recourse to wholesome dust and wipe your faces and your hands ; God is All-pardoning , All-forgiving .
