Noble Shaykh,

My question is if a husband makes a promise when he marries a sister (who was new to Islam) that he would not take a second wife and then changes his mind later in the marriage, does the first wife have to accept this or does she have the right to divorce based on this lie. Although the wife now knows that the husband should not have made this promise because he does not know Allah's decree for himself, but the wife did not know this at the time. The wife also knows that she cannot ask the husband to uphold his original promise because she cannot make something haram which Allah has made halal. Jazakamallahu khairun...
