The food of the People of the Book is lawful unto you and yours is lawful unto them . ( Lawful unto you in marriage ) are ( not only ) chaste women who are believers , but chaste women among the People of the Book , revealed before your time , - when ye give them their due dowers , and desire chastity , not lewdness , nor secret intrigues if any one rejects faith , fruitless is his work , and in the Hereafter he will be in the ranks of those who have lost ( all spiritual good ) .
