This day (all) good things are made lawful for you. And the food of those who have been given the Book is lawful for you and your food is lawful for them. And so are the chaste from among the believing women and the chaste from among those who have been given the Book before you, when you give them their dowries, taking (them) in marriage, not fornicating nor taking them for paramours in secret. And whoever denies faith, his work indeed is vain; and in the Hereafter he is of the losers.
