Al-Báqara 2:221 ولا تنكحوا المشركات حتى يومن ولامة مومنة خير من مشركة ولو اعجبتكم ولا تنكحوا المشركين حتى يومنوا ولعبد مومن خير من مشرك ولو اعجبكم اولايك يدعون الى النار والله يدعو الى الجنة والمغفرة باذنه ويبين اياته للناس لعلهم يتذكرون ٢٢١

Wed not idolatresses till they believe; for lo! a believing bondwoman is better than an idolatress though she please you; and give not your daughters in marriage to idolaters till they believe, for lo! a believing slave is better than an idolater though he please you. These invite unto the Fire, and Allah inviteth unto the Garden, and unto forgiveness by His grace, and expoundeth His revelations to mankind that haply they may remember.

Do not marry unbelieving women (idolaters), until they believe: A slave woman who believes is better than an unbelieving woman, even though she allures you. Nor marry (your girls) to unbelievers until they believe: A man slave who believes is better than an unbeliever, even though he allures you. Unbelievers do (but) beckon you to the Fire. But Allah beckons by His Grace to the Garden (of bliss) and forgiveness, and makes His Signs clear to mankind: That they may celebrate His praise.
