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.

5:49And judge between them according to what God revealed, and do not follow their desires. And beware of them, lest they lure you away from some of what God has revealed to you. But if they turn away, know that God intends to strike them with some of their sins. In fact, a great many people are corrupt.
