5:3Prohibited for you are carrion, blood, the flesh of swine, and animals dedicated to other than God; also the flesh of animals strangled, killed violently, killed by a fall, gored to death, mangled by wild animals—except what you rescue, and animals sacrificed on altars; and the practice of drawing lots. For it is immoral. Today, those who disbelieve have despaired of your religion, so do not fear them, but fear Me. Today I have perfected your religion for you, and have completed My favor upon you, and have approved Islam as a religion for you. But whoever is compelled by hunger, with no intent of wrongdoing—God is Forgiving and Merciful.

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.
