And do not marry the idolatresses until they believe, and certainly a believing maid is better than an idolatress woman, even though she should please you; and do not give (believing women) in marriage to idolaters until they believe, and certainly a believing servant is better than an idolater, even though he should please you; these invite to the fire, and Allah invites to the garden and to forgiveness by His will, and makes clear His communications to men, that they may be mindful.

Then We gave the Book for an inheritance to those whom We chose from among Our servants; but of them is he who makes his soul to suffer a loss, and of them is he who takes a middle course, and of them is he who is foremost in deeds of goodness by Allah's permission; this is the great excellence.
