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.

5:41O Messenger! Do not let those who are quick to disbelief grieve you—from among those who say with their mouths, “We believe,” but their hearts do not believe; and from among the Jews—listeners to lies, listeners to other people who did not come to you. They distort words from their places, and they say, “If you are given this, accept it; but if you are not given it, beware.” Whomever God has willed to divert, you have nothing for him from God. Those are they whose hearts God does not intend to purify. For them is disgrace in this world, and for them is a great punishment in the Hereafter.
