Yahya related to me from Malik from Abd ar-Rahman ibn al-Qasim that his father told him that A'isha, the wife of the Prophet, may Allah bless him and grant him peace, admitted those whom her sisters and the daughters of her brother had nursed, and she did not admit those who were nursed by the wives of her brothers.

وَحَدَّثَنِي عَنْ مَالِكٍ، عَنْ عَبْدِ الرَّحْمَنِ بْنِ الْقَاسِمِ، عَنْ أَبِيهِ، أَنَّهُ أَخْبَرَهُ أَنَّ عَائِشَةَ زَوْجَ النَّبِيِّ صلى الله عليه وسلم كَانَ يَدْخُلُ عَلَيْهَا مَنْ أَرْضَعَتْهُ أَخَوَاتُهَا وَبَنَاتُ أَخِيهَا وَلاَ يَدْخُلُ عَلَيْهَا مَنْ أَرْضَعَهُ نِسَاءُ إِخْوَتِهَا ‏.‏
