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."
عَنْ عَائِشَةَ زَوْجِ النَّبِيِّ ﷺ أَنَّهَا قَالَتْ كَانَ فِيمَا أُنْزِلَ مِنَ الْقُرْآنِ عَشْرُ رَضَعَاتٍ مَعْلُومَاتٍ يُحَرِّمْنَ ثُمَّ نُسِخْنَ بِخَمْسٍ مَعْلُومَاتٍ فَتُوُفِّيَ رَسُولُ اللَّهِ ﷺ وَهُوَ فِيمَا يُقْرَأُ مِنَ الْقُرْآنِ
