أَخْبَرَنَا عُبَيْدُ اللَّهِ بْنُ سَعِيدٍ، قَالَ حَدَّثَنَا يَحْيَى، قَالَ حَدَّثَنَا هِشَامٌ، قَالَ حَدَّثَنَا مُحَمَّدٌ، عَنْ أَبِي هُرَيْرَةَ، عَنِ النَّبِيِّ صلى الله عليه وسلم قَالَ لاَ تُنْكَحُ الْمَرْأَةُ عَلَى عَمَّتِهَا وَلاَ عَلَى خَالَتِهَا .
It was narrated from Abu Hurairah that the Messenger of Allah said: "A woman should not be taken as a co-wife to her paternal aunt or her maternal aunt."
