Quran 5:6 — The Feast (Al-Ma'edah)

O you who believe, when you observe the Contact Prayers (Salat), you shall: (1) wash your faces, (2) wash your arms to the elbows, (3) wipe your heads, and (4) wash your feet to the ankles. If you were unclean due to sexual orgasm, you shall bathe. If you are ill, or traveling, or had any digestive excretion (urinary, fecal, or gas), or had (sexual) contact with the women, and you cannot find water, you shall observe the dry ablution (Tayammum) by touching clean dry soil, then rubbing your faces and hands. GOD does not wish to make the religion difficult for you; He wishes to cleanse you and to perfect His blessing upon you, that you may be appreciative.

[5:5] Today, all good food is made lawful for you. The food of the people of the scripture is lawful for you. Also, you may marry the chaste women among the believers, as well as the chaste women among the followers of previous scripture, provided you pay them their due dowries. You shall maintain chastity, not committing adultery, nor taking secret lovers. Anyone who rejects faith, all his work will be in vain, and in the Hereafter he will be with the losers.

[5:7] Remember GOD's blessing upon you, and His covenant that He covenanted with you: you said, "We hear and we obey." You shall observe GOD; GOD is fully aware of the innermost thoughts.
