As for your women past the age of menstruation, in case you do not know, 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.
— Dr. Mustafa Khattab, the Clear Quran
And those who no longer expect menstruation among your women - if you doubt, then their period is three months, and [also for] those who have not menstruated. And for those who are pregnant, their term is until they give birth.1 And whoever fears Allah - He will make for him of his matter ease.
