A woman should not marry a man already married to her paternal aunt
Arabic hadith text
حَدَّثَنَا عَبْدُ اللَّهِ بْنُ يُوسُفَ، أَخْبَرَنَا مَالِكٌ، عَنْ أَبِي الزِّنَادِ، عَنِ الأَعْرَجِ، عَنْ أَبِي هُرَيْرَةَ، رضى الله عنه أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم قَالَ ‏"‏لاَ يُجْمَعُ بَيْنَ الْمَرْأَةِ وَعَمَّتِهَا، وَلاَ بَيْنَ الْمَرْأَةِ وَخَالَتِهَا ‏"
Translation
Narrated Abu Huraira

Allah's Messenger (ﷺ) said, "A woman and her paternal aunt should not be married to the same man; and similarly, a woman and her maternal aunt should not be married to the same man."
