In verse 33:49 of the Holy Quran, Allah (swt) says,
“O you who believe! When you marry the believing women, then you divorce before you touch them, you have in their case no term which you should reckon; so make some provision for them and send them forth a goodly sending forth”.
The women who are in question here are the ones who have been divorced before the consummation of their marriage. Such women do not have to observe an iddat/waiting period. If they wish, they can marry immediately after the divorce, without any waiting period.
However, the waiting period will not be cancelled if (after the divorce) the husband dies before the consummation of marriage. In such a case the women will have to observe iddat/waiting period of four months and ten days, as it is compulsory for the married women under normal circumstances.
Though in this verse, the men are empowered with the right to divorce yet they are also dissuaded from misusing this power by making it obligatory for them to pay half the dower. This means that when a man divorces his wife before having sexual intercourse with her, he will be expected to pay half the dower which may have been fixed at the time of the marriage. This places a financial burden on the man which may deter him from divorcing his wife on flimsy grounds.
Keep Me In Your Prayers.
