However if this women was to be pregnant then she must wait until she delivers her
baby this is the time she can remarry. Before we clarify the reason, one should say to
ones self : look how detailed the Quran is in one issue regarding women.
If one wants to understand the logic of the Quran it is simply just to make her free
from her previous husband that he is not the father of any child thereafter.
As Allah says:
Nor is it lawful for them to hide what Allah Hath created in their wombs,
[The Cow Verse 228]
As three consecutive periods will demonstrate to her that she is not pregnant.
Allah says:
and for those who have no courses (it is the same): for those who carry (life within
their wombs), their period is until they deliver their burdens: and for those who fear
Allah, He will make their path easy.
[The Divorce Verse 4]
Where is the miracle it is initially hard to spot it is in the three months, as a women
may see a period or two whilst being pregnant but if she doesn’t see the third period
it is certain that she is pregnant.
And their husbands have the better right to take them back in that period, if they
wish for reconciliation.
[The Cow Verse 228]
As for the second verse then the miracle is in the fact that only after four months
and ten days does the baby start to move and the mother becomes aware of the
movement, so it confirms whether or not that mother is pregnant.
If after four months and ten day she feels nothing it is likely the baby has died and
should be removed y the necessary medical means.
As for the women who know they are pregnant Allah says:
for those who carry (life within their wombs), their period is until they deliver their
burdens:
[The Divorce Verse 4]
In order to complete the point:
but if they leave (The residence), there is no blame on you for what they do with
themselves, provided it is reasonable. And Allah is Exalted in Power, Wise.
