O you who have faith! When you stand up for prayer, wash your faces and your hands up to the elbows, and wipe a part of your heads and your feet, up to the ankles. If you are junub, purify yourselves. But if you are sick, or on a journey, or any of you has come from the toilet, or you have touched women, and you cannot find water, then make tayammum with clean ground and wipe a part of your faces and your hands with it. Allah does not desire to put you to hardship, but He desires to purify you, and to complete His blessing upon you so that you may give thanks.
