Iddat is the period which a Muslim woman has to observe after dissolution of marriage. During this period woman has to remain in seclusion and is abstained from marrying another person or, it can also be said that, during this period woman is prohibited from marrying again after dissolution of her first marriage. The object of Iddat is to ascertain the pregnancy of the wife so as to avoid confusion of parentage (paternity of child) and to give time after Talaq to both the couple so that they can reconcile or re-think about their relationship and can decide whether to dissolve the marriage or to revoke the Talaq pronounced. The completion of Iddat will make Talaq irrevocable.
