Ruju Option After Third Divorce
Divorce is a serious decision. It is not considered valid if done in a state of fury or some kind of insanity. If you divorced your wife with serious intention, every time, not in a state of fury or insanity, then every divorce is valid, if not, then you have to prove with evidence or an oath that you did not intend to divorce, and the an arbitrator may decide the divorce is valid or invalid. If this is done with serious intention, then after the third time, you cannot take her back with or without Nikah, unless, she gets married to someone else and if she is divorced by him, then you can marry her if she is willing.
