Ablutions (Washing)

O believers! When you rise for prayer, wash your faces, hands to the elbows, wipe your heads, and wash your feet to the ankles. If impure, purify yourselves. If ill, traveling, or unable to find water, use clean earth and wipe your faces and hands. Allah does not burden you but seeks to purify and complete His favour upon you, so you may be grateful.

5:6O ye who believe! When ye rise up for prayer, wash you faces, and your hands up to the elbows, and lightly rub your heads and (wash) your feet up to the ankles. And if ye are unclean, purify yourselves. And if ye are sick or on a journey, or one of you cometh from the closet, or ye have had contact with women, and ye find not water, then go to clean, high ground and rub your faces and your hands with some of it. Allah would not place a burden on you, but He would purify you and would perfect His grace upon you, that ye may give thanks.
