Quran 2:226 — The Heifer (Al-Baqarah)

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.

[2:225] GOD does not hold you responsible for the mere utterance of oaths; He holds you responsible for your innermost intentions. GOD is Forgiver, Clement.

[2:227] If they go through with the divorce, then GOD is Hearer, Knower.
