that Messenger of Allah ﷺ forbade combining of four women in marriage: a woman with her father's sister, and a woman with her mother's sister. (Using translation from Muslim 1408b)
أَنَّ رَسُولَ اللهِ ﷺ «نَهَى عَنْ أَرْبَعِ نِسْوَةٍ أَنْ يُجْمَعَ بَيْنَهُنَّ الْمَرْأَةُ وَعَمَّتُهَا وَالْمَرْأَةُ وَخَالَتُهَا»
