Dignity, independence and woman's property rights

O believers, you are not allowed to take perforce the women (of dead relatives) into your heritage, or tyrannise over them in order to deprive them of what you have given them, unless they are guilty of open adultery. Live with them with tolerance and justice even if you do not care for them. For it may well be you may not like a thing, yet God may have endued it with much goodness.

If you want to take another wife in place of the one you are married to, then even if you have given her a talent of gold, do not take back a thing. Would you take it away by slandering and using unjust means?

How could you do that having slept with one another, and when they had taken a solemn pledge from you?
