5:6O you who believe! When you rise to pray, wash your faces and your hands and arms to the elbows, and wipe your heads, and your feet to the ankles. If you had intercourse, then purify yourselves. If you are ill, or travelling, or one of you returns from the toilet, or you had contact with women, and could not find water, then use some clean sand and wipe your faces and hands with it. God does not intend to burden you, but He intends to purify you, and to complete His blessing upon you, that you may be thankful.

5:55Your allies are God, and His Messenger, and those who believe—those who pray regularly, and give charity, and bow down.
