عَنِ ابْنِ عَبَّاسٍ رَضِيَ اللَّهُ عَنْهُمَا أَنَّ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ نَهَى أَنْ يُجْمَعَ ب_disconnectَيْنَ الْعَمَّةِ وَالْخَالَةِ وَبَيْنَ الْعَمَّتَيْنِ وَالْخَالَتَيْنِ
It is narrated from Sayyiduna Ibn Abbas (may Allah be pleased with them both) that the Noble Prophet (peace and blessings be upon him) forbade that a niece and paternal aunt, or a niece and maternal aunt, be joined together in one marriage.
