The prohibition of being married to a woman and her paternal aunt or maternal aunt at the same time
وَحَدَّثَنَا عَبْدُ اللَّهِ بْنُ مَسْلَمَةَ بْنِ قَعْنَبٍ، حَدَّثَنَا عَبْدُ الرَّحْمَنِ بْنُ عَبْدِ الْعَزِيزِ، - قَالَ ابْنُ مَسْلَمَةَ مَدَنِيٌّ مِنَ الأَنْصَارِ مِنْ وَلَدِ أَبِي أُمَامَةَ بْنِ سَهْلِ بْنِ حُنَيْفٍ - عَنِ ابْنِ شِهَابٍ، عَنْ قَبِيصَةَ بْنِ ذُؤَيْبٍ، عَنْ أَبِي هُرَيْرَةَ، قَالَ سَمِعْتُ رَسُولَ اللَّهِ صلى الله عليه وسلم يَقُولُ " لاَ تُنْكَحُ الْعَمَّةُ عَلَى بِنْتِ الأَخِ وَلاَ ابْنَةُ الأُخْتِ عَلَى الْخَالَةِ " .
Abu Huraira (Allah be pleased with him) reported: I heard Allah's Messenger (ﷺ) say: Father's sister should not be combined with her brother's daughter, nor the daughter of a sister with her mother's sister.
