The prohibition of being married to a woman and her paternal aunt or maternal aunt at the same time Sahih Muslim 1408 h
Translation
Abu Huraira (Allah be pleased with him) reported that Allah's Messenger (ﷺ) forbade the combining of a woman in marriage with her father's sister, or with her mother's sister, or that a woman should ask for divorce for her sister in order to deprive her of what belongs to her. Allah, the Exalted'and Majestic, is her Sustainer too.
