The Book of Marriage
16/4. Chapter:
The prohibition of being married to a woman and her paternal aunt or maternal aunt at the same time
Sahih Muslim
وَحَدَّثَنِي حَرْمَلَةُ بْنُ يَحْيَى، أَخْبَرَنَا ابْنُ وَهْبٍ، أَخْبَرَنِي يُونُسُ، عَنِ ابْنِ شِهَابٍ، أَخْبَرَنِي قَبِيصَةُ بْنُ ذُؤَيْبٍ الْكَعْبِيُّ، 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 Huraira (Allah be pleased with him) reported that Allah's Messenger (ﷺ) forbade a person to combine in marriage a womanarid her father's sister, and a woman and her mother's sister. Ibn Shihab said: So we regarded the paternal aunt of her (wife's) father and the maternal aunt of her (wife's) father at the same level.
