وَحَدَّثَنِى حَرْمَلَةُ بْنُ يَحْيَى أَخْبَرَنَا ابْنُ وَهْبٍ أَخْبَرَنِى يُونُسُ عَنِ ابْنِ شِهَابٍ أَخْبَرَنِى قَبِيصَةُ بْنُ ذُؤَيْبٍ الْكَعْبِىُّ أَنَّهُ سَمِعَ أَبَا هُرَيْرَةَ يَقُولُ نَهَى رَسُولُ اللَّهِ -صلى الله عليه وسلم- أَنْ يَجْمَعَ الرَّجُلُ بَيْنَ الْمَرْأَةِ وَعَمَّتِهَا وَبَيْنَ الْمَرْأَةِ وَخَالَتِهَا. قَالَ ابْنُ شِهَابٍ فَنُرَى خَالَةَ أَبِيهَا وَعَمَّةَ أَبِيهَا بِتِلْكَ الْمَنْزِلَةِ.

Abu Hurairah said: "The Messenger of Allah (s.a.w) forbade a man to be married to a woman and her paternal aunt, or to a woman and her maternal aunt." Ibn Shihab said: "We think that the maternal aunt of her father and the paternal aunt of her father come under the same ruling."
