عَنْ أَبِي هُرَيْرَةَ قَالَ: قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ: «لَا يُجْمَعُ بَيْنَ الْمَرْأَة وعمتها وَلَا بَين الْمَرْأَة وخالتها»

‘A’isha reported God’s Messenger as saying, “What is unlawful by reason of consanguinity is unlawful by reason of fosterage.” Bukhari transmitted it.
