I married a woman but we have not

A: It is impermissible to have these two wives in wedlock at the same time, as the first wife is the aunt of the second wife's father. In Islam, the aunt of the father is the aunt of his children. It was authentically reported that the Messenger of Allah (peace be upon him) forbade a man to marry (Part No. 18; Page No. 243) a woman and her aunt at the same time. However, it is permissible to divorce the first wife and to marry the second one after the `Iddah (woman's prescribed waiting period after divorce) is over. May Allah grant us success. May peace and blessings of Allah be upon our Prophet Muhammad, his family and Companions!
