Quran 2:227 — The Heifer (Al-Baqarah)

If they go through with the divorce, then GOD is Hearer, Knower.

[2:226] Those who intend to divorce their wives shall wait four months (cooling off); if they change their minds and reconcile, then GOD is Forgiver, Merciful.

[2:228] The divorced women shall wait three menstruations (before marrying another man). It is not lawful for them to conceal what GOD creates in their wombs, if they believe in GOD and the Last Day. (In case of pregnancy,) the husband's wishes shall supersede the wife's wishes, if he wants to remarry her. The women have rights, as well as obligations, equitably. Thus, the man's wishes prevail (in case of pregnancy). GOD is Almighty, Most Wise.
