Other translations of verse 221
Do not marry polytheist women until they believe; for a believing slave woman is better than a free polytheist, even though she may attract you. And do not give your women in marriage to polytheist men until they believe, for a believing slave is better than a free polytheist, even though he may attract you. They invite to the Fire while Allah invites to Paradise and to forgiveness by His grace, and He makes His verses clear to people so that they may take heed114.
Notes

And do not marry Al-Mushrikât (idolatresses, etc.) till they believe (worship Allâh Alone). And indeed a slave woman who believes is better than a (free) Mushrikah (idolatress), even though she pleases you. And give not (your daughters) in marriage to Al-Mushrikûn56 till they believe (in Allâh Alone) and verily, a believing slave is better than a (free) Mushrik (idolater), even though he pleases you. Those (Al-Mushrikûn) invite you to the Fire, but Allâh invites (you) to Paradise and Forgiveness by His Leave, and makes His Ayât (proofs, evidence, verses, lessons, signs, revelations, etc.) clear to mankind that they may remember.

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.
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.
And do not marry female associators (Those who associate others with Allah) until they believe; and indeed a believing bondwoman is more charitable than a female associator, even if you may admire her. And do not (allow) associators to marry (your females) until they believe. And indeed a believing bondman is more charitable than an associator, even if you may admire him. Those call to the Fire, and Allah calls to the Garden and forgiveness, by His permission, and He makes evident His signs to mankind, that possibly they would remind themselves.
