Observing Iddah
Question :

If a man waives the remaining time in a temporary marriage which was consummated, then after a few days the same man and woman engage in another temporary marriage which is not consummated, will the women have to observe the waiting period after it ends?

Answer :

When the marriage is consummated and the time of the temporary marriage is finished or the husband forgoes the remaining time of marriage, if the couple wanted to remarry again then the woman does not have to undertake the waiting period, iddah. If the woman wanted to marry another man, she is not permitted to do so unless she observes the waiting period of the marriage with the previous husband.
