وَاللّائي يَئِسنَ مِنَ المَحيضِ مِن نِسائِكُم إِنِ ارتَبتُم فَعِدَّتُهُنَّ ثَلاثَةُ أَشهُرٍ وَاللّائي لَم يَحِضنَ ۚ وَأُولاتُ الأَحمالِ أَجَلُهُنَّ أَن يَضَعنَ حَملَهُنَّ ۚ وَمَن يَتَّقِ اللَّهَ يَجعَل لَهُ مِن أَمرِهِ يُسرًا

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. And whoever fears Allah - He will make for him of his matter ease.
