O you who believe! When you rise up to prayer wash your faces, and your hands as far as the elbows, and wipe your heads, and your feet down to the ankles. And if you are polluted, then purify yourselves (bathe). But if you are sick, or on a journey, or if you come from the toilet, or if you have touched women and cannot find water, then take from high ground (clean) sand or earth and wipe your faces and your hands therewith. Allah does not wish to make a burden for you; but He wishes to purify you and to fulfil his favour upon you; that you may give thanks.
