ضَرَبَ ٱللَّهُ مَثَلًۭا لِّلَّذِينَ كَفَرُوا۟ ٱمْرَأَتَ نُوحٍۢ وَٱمْرَأَتَ لُوطٍۢ ۖ كَانَتَا تَحْتَ عَبْدَيْنِ مِنْ عِبَادِنَا صَٰلِحَيْنِ فَخَانَتَاهُمَا فَلَمْ يُغْنِيَا عَنْهُمَا مِنَ ٱللَّهِ شَيْـًۭٔا وَقِيلَ ٱدْخُلَا ٱلنَّارَ مَعَ ٱلدَّٰخِلِينَ
Allah citeth an example for those who disbelieve: the wife of Noah and the wife of Lot, who were under two of Our righteous slaves yet betrayed them so that they (the husbands) availed them naught against Allah and it was said (unto them): Enter the Fire along with those who enter.
Surah At-Tahrim(66:10)

Wedlock, Marriage (Nikaah)
Chapter: A woman should not marry a man already married to her paternal aunt
Narrated Abu Huraira:
The Prophet (ﷺ) forbade that a woman should be married to a man along with her paternal aunt or with her maternal aunt (at the same time). Az-Zuhri (the sub-narrator) said: There is a similar order for the paternal aunt of the father of one's wife, for 'Urwa told me that `Aisha said, "What is unlawful because of blood relations, is also unlawful because of the corresponding foster suckling relations."
