The Cow - 2:232
When the divorced women have finished their waiting period, do not prevent them from remarrying if they agree with their husbands in goodness. Those of you who believe in Allah and the Last Day take admonition from this. That is purer and healthier for you. Allah knows, even if you do not know.
If you marry women and divorce them without sexual intercourse:
The Coalition/33:49
O you who believe, if you divorce believing women after you have married them and have not had sexual intercourse with them, they do not owe you a waiting period (before they marry another).
The Cow/2:236
It is permissible for you to divorce women before you have touched them or before they have paid their mahr. In that case, pay them. The rich should compensate them according to their means, and the poor should compensate them according to their means. This is the duty of the righteous.
The Cow/2:237
If you have divorced them after you have paid the bride price, but before you have touched them, you should give them half of the promised bride price. Unless the wife renounces her right or the husband wants to give the full amount. It is more virtuous for you to give it up. Remember the friendship between you. Allah is All-Seeing of what you do.
