Al-Baqarah · 2:236

236. There is no sin on you if you divorce your wives with whom you have entered into marriage before you have sexual intercourse with them and before you fix a dowry for them. If you must divorce them in such a situation, they will not be entitled to any dowry from you; but they must be given something that they will enjoy, to make it easy on their feelings. This must be done by both a rich and a poor man according to their means. This gift is binding on those who wish to do good in their actions and dealings.
