Muwatta Malik, Book 28, Hadith 1114 (In-Book)

Yahya related to me from Malik from Abu'z-Zinad from al-Araj from Abu Hurayra that the Messenger of Allah, may Allah bless him and grant him peace, said "One cannot be married to a woman and her paternal aunt, or a woman and her maternal aunt at the same time."

وَحَدَّثَنِي يَحْيَى، عَنْ مَالِكٍ، عَنْ أَبِي الزِّنَادِ، عَنِ الأَعْرَجِ، عَنْ أَبِي هُرَيْرَةَ، أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم قَالَ ‏ "‏ لاَ يُجْمَعُ بَيْنَ الْمَرْأَةِ وَعَمَّتِهَا وَلاَ بَيْنَ الْمَرْأَةِ وَخَالَتِهَا ‏" ‏ ‏.‏
