O YOU who have attained to faith! When you are about to pray, wash your face, and your hands and arms up to the elbows, and pass your [wet] hands lightly over your head, and [wash] your feet up to the ankles. And if you are in a state. requiring total ablution, purify yourselves. But if you are ill, or are travelling, or have just satisfied a want of nature, or have cohabited with a woman, and can find no water-then take resort to pure dust, passing therewith lightly over your face and your hands. God does not want to impose any hardship on you, but wants to make you pure, and to bestow upon you the full measure of His blessings, so that you might have cause to be grateful.
