Marrying a woman and her aunt at the same time

Q: The Messenger of Allah (peace be upon him) said: "Do not combine between a woman and her paternal aunt or between a woman and her maternal aunt." (Agreed upon by Al-Bukhari and Muslim) Is it permissible to marry a woman and the mother of her maternal aunt?

A: If the mother of the wife's maternal aunt happens to be her grandmother, it is not permissible to take her in marriage together with the wife. This is only permissible if the mother of the wife's maternal aunt is not her grandmother; like in the case where the maternal aunt happens to be a paternal sister of the wife's mother. May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
