Hadith 16:39
Abu Huraira (Allah be pleased with him) reported Allah's Messenger (may peace upon him) having said this:
One should not combine a woman and her father's sister, nor a woman and her mother's sister in marriage.
حَدَّثَنَا عَبْدُ اللَّهِ بْنُ مَسْلَمَةَ الْقَعْنَبِيُّ، حَدَّثَنَا مَالِكٌ، عَنْ أَبِي الزِّنَادِ، عَنِ الأَعْرَجِ، عَنْ أَبِي هُرَيْرَةَ، قَالَ قَالَ رَسُولُ اللَّهِ " لاَ يُجْمَعُ بَيْنَ الْمَرْأَةِ وَعَمَّتِهَا وَلاَ بَيْنَ الْمَرْأَةِ وَخَالَتِهَا"
