In the Glorious Qur’an, Almighty Allah said: (And the divorced women should keep themselves in waiting for three monthly periods; and it is not lawful for them that they should conceal what Allah has created in their wombs, if they believe in Allah and the last day; and their husbands have a better right to take them back in the meanwhile if they wish for reconciliation; and they have rights similar to those over them in a just manner, and the men are a degree above them, and Allah is Mighty, Wise. Divorce may be (pronounced) twice, then keep (them) in good fellowship or release in kindness) (al-Bqarah 2:228-229)
Muslim jurists have thus unanimously agreed that a Muslim husband have the right to divorce his wife three times. After each of the first two divorces, he may take back his wife into wedlock during the waiting period (`iddah) without the necessity of making a new marriage contract. But if the waiting period elapses, then a new marriage contract has to be concluded.
The third time of divorce is the final one after which the husband has no right to tack back his wife into wedlock neither during her waiting period nor after its termination.
Therefore, a Muslim should fear Allah and watch his tongue so as not to undermine his family because of his foolishness or recklessness. Divorce terms cannot be used for threatening or warnings. Once a husband divorces his wife the divorce takes effect.
