The principle laid down regarding the time when talaq become effective in the case of a pregnant woman is that followed in the case of talaq-i-ahsan. It is to be noted that talaq-e-ahsan becomes irrevocable at the end of the period of iddat. But during that period the husband can take back his wife at any time. When the woman is not subject to courses the talaq can be pronounced even after cohabitation. The divorce become irrevocable only on the completion of iddat which is three periods and when the woman is not subject to periods it is three months. When the woman is pregnant the iddat becomes to an end on the delivery of the child or three months whichever is later. But in a late decision it has been held that the provision of talaq being made effective in case of a pregnant divorce to end with pregnancy or three months whichever is later is manifestly repugnant to the injunctions of the Holy Quran and Sunnah. Object of waiting period is cleaning the womb which is the best achieved by delievery..
