Is it permissible to marry another woman without informing the first wife and the mother, in order to avoid a request for divorce and out of fear of the mother, while having the desire to marry her and invite her family to Islam?

We believe it is better for you not to marry this woman, and to preserve your first wife and your children; because the harm of divorce is greater than the benefit of your marriage to a second wife. However, if you are in need of marrying her, there is no sin upon you, whether you inform your wife and mother or not, with the necessity of deliberation, careful consideration, and looking into the consequences.
