Yahya related to me from Malik from Abdullah ibn Abi Bakr ibn Hazm from Amra bint Abd ar-Rahman that A'isha, the wife of the Prophet, (ﷺ), said, "Amongst what was sent down of the Qur'an was 'ten known sucklings make haram' - then it was abrogated by 'five known sucklings'. When the Messenger of Allah, (ﷺ), died, it was what is now recited of the Qur'an." Yahya said that Malik said, "One does not act on this."

وَحَدَّثَنِي عَنْ مَالِكٍ، عَنْ عَبْدِ اللَّهِ بْنِ أَبِي بَكْرِ بْنِ حَزْمٍ، عَنْ عَمْرَةَ بِنْتِ عَبْدِ الرَّحْمَنِ، عَنْ عَائِشَةَ، زَوْجِ النَّبِيِّ صلى الله عليه وسلم أَنَّهَا قَالَتْ كَانَ فِيمَا أُنْزِلَ مِنَ الْقُرْآنِ عَشْرُ رَضَعَاتٍ مَعْلُومَاتٍ يُحَرِّمْنَ ثُمَّ نُسِخْنَ بِخَمْسٍ مَعْلُومَاتٍ فَتُوُفِّيَ رَسُولُ اللَّهِ صلى الله عليه وسلم وَهُوَ فِيمَا يُقْرَأُ مِنَ الْقُرْآنِ ‏.‏
