It was narrated from Abu Hurairah that the Messenger of Allah forbade being married to four kinds of women at the same time:

a woman and her paternal aunt or a woman and her maternal aunt.

أَخْبَرَنَا قُتَيْبَةُ، قَالَ حَدَّثَنَا اللَّيْثُ، عَنْ يَزِيدَ بْنِ أَبِي حَبِيبٍ، عَنْ عِرَاكِ بْنِ مَالِكٍ، عَنْ أَبِي هُرَيْرَةَ، أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم نَهَى عَنْ أَرْبَعِ نِسْوَةٍ يُجْمَعُ بَيْنَهُنَّ الْمَرْأَةِ وَعَمَّتِهَا وَالْمَرْأَةِ وَخَالَتِهَا ‏.‏
