As for your women past the age of menstruation, in case you are not sure, their waiting period is three months, and those who have not menstruated as well. As for those who are pregnant, their waiting period ends with delivery.¹ And whoever is mindful of Allah, He will make their matters easy for them.

And those of your women as have passed the age of monthly courses, for them the ‘Iddah (prescribed period), if you have doubt (about their periods), is three months; and for those who have no courses [(i.e. they are still immature) their ‘Iddah (prescribed period) is three months likewise, except in case of death]¹. And for those who are pregnant (whether they are divorced or their husbands are dead), their ‘Iddah (prescribed period) is until they lay down their burden; and whosoever fears Allâh and keeps his duty to Him, He will make his matter easy for him.
