2:221 Do not marry unbelieving women (idolaters) until they believe; a slave woman who believes is better than an unbelieving woman even though she allure you. Nor marry (your girls) to unbelievers until they believe: a man slave who believes is better than un unbeliever even though he allure 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.
The worst of men on the day of resurrection will be the two faced man who went to one people with one face and to others with another face. (Bukhari & Muslim)
