5:5Today all good things are made lawful for you. And the food of those given the Scripture is lawful for you, and your food is lawful for them. So are chaste believing women, and chaste women from the people who were given the Scripture before you, provided you give them their dowries, and take them in marriage, not in adultery, nor as mistresses. But whoever rejects faith, his work will be in vain, and in the Hereafter he will be among the losers.

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.
