If a man divorces his wife on a third different time during their marital life, it shall be unlawful for him to remarry her. It may so happen that the woman marries another man, and those two do not get along, and the other husband divorces her. In that case, there is nothing wrong if both (the previous couple) decide to come together again, if they consider that they will be able to observe the Limits set by Allah. These Limits have been made clear to enable people to make use of the Divine gift of knowledge.
