Marrying
If any of your wives leave you for the disbelievers, and you later gain something from them, then give those whose wives left the equivalent of what they spent.
60:11And if any of your wives have gone from you unto the disbelievers and afterward ye have your turn (of triumph), then give unto those whose wives have gone the like of that which they have spent, and keep your duty to Allah in Whom ye are believers.
