A wife repeatedly demanding divorce while the husband refuses

Question:
If my wife asks me for a divorce several times and I refuse, is this injustice or not? If my wife asks me for a divorce many times and I refuse, is this injustice? And if I marry secretly without my wife’s knowledge, is there anything on me?

Answer:
If you are asked for a divorce for a reason, because you have failed in your rights toward her, or you have not treated her with what is due, or you are being unjust to her, then it is obligatory to remove this great harm, either by being just or by divorcing her. [Retaining her] with kindness or [releasing her] with generosity. As for if the request for divorce is without a reason, it is not permissible for her to do this. Any woman in the authentic hadith , and I am severe in this; it is not permissible for her to ask for a divorce without a reason. Yes.
