Quran 2:237 – Surah Al-Baqarah (The Cow)

And if you divorce them before you have touched them, and you have already appointed for them an obligation, then one-half of what you have appointed, must be given to them and the other half returns to you; unless it be that they, the women, make remission, and forgo it, or he makes remission, by leaving her the entire amount, the one in whose hand is the knot of marriage, the husband to be, or as Ibn ‘Abbās is reported to have said, ‘The legal guardian, where the female is a minor’; in which case nobody would be at fault; yet that you should remit (wa-an ta‘fū is the subject) is nearer to piety (aqrabu li’l-taqwā is its predicate). Forget not kindness between you, that is, to be bountiful towards one another; surely God sees what you do, and will requite you accordingly.
