Surah 2

Surah 2:237

"If you divorce them before you have touched them, but you have already promised them a bridal gift, (give them) half of what you have promised, unless they relinquish (it), or he relinquishes (it) in whose hand is the knot of marriage. To relinquish (it) is nearer to the guarding (of oneself), and do not forget generosity among you. Surely God sees what you do."
