O believers, when you stand up to pray wash your faces, and your hands up to the elbows, and wipe your heads, and your feet up to the ankles. If you are defiled, purify 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 with it. God does not desire to make any impediment for you; but He desires to purify you, and that He may complete His blessing upon you; haply you will be thankful.
