Do not marry idolatresses until they embrace faith. A faithful slave girl is better than an idolatress, though she should impress you. And do not marry [your daughters] to idolaters until they embrace faith. A faithful slave is better than an idolater, though he should impress you. Those invite [others] to the Fire, but Allah invites to paradise and pardon, by His will, and He clarifies His signs for the people so that they may take admonition.
