Al-Baqarah - 2:227

وَإِنْ عَزَمُواْ الطَّلاَقَ فَإِنَّ اللّهَ سَمِيعٌ عَلِيمٌ
[2:227]
And if they have resolved on a divorce, then Allah is surely Hearing, Knowing.
But if their intention is firm for divorce, Allah heareth and knoweth all things.
And if they decide upon divorce (let them remember that) Allah is Hearer, Knower.
