Marriage
وَعَنْ أَبِي هُرَيْرَةَ - رضى الله عنه - أَنَّ اَلنَّبِيَّ - صلى الله عليه وسلم -قَالَ : { لَا يُجْمَعُ بَيْنَ اَلْمَرْأَةِ وَعَمَّتِهَا , وَلَا بَيْنَ اَلْمَرْأَةِ وَخَالَتِهَا } مُتَّفَقٌ عَلَيْهِ [1] .
Narrated Abu Hurairah (RA): Allah's Messenger (ﷺ) said: "A man must not join together (in marriage to him) a woman and her paternal aunt or a woman and her maternal aunt." [Agreed upon].
