“Once of the things that Allah revealed in the the Qur'an and then abrogated was that nothing makes marriage prohibited except ten breastfeedings or five well-known (breastfeedings).”
أَنَّهَا قَالَتْ كَانَ فِيمَا أَنْزَلَ اللَّهُ مِنَ الْقُرْآنِ ثُمَّ سَقَطَ لاَ يُحَرِّمُ إِلاَّ عَشْرُ رَضَعَاتٍ أَوْ خَمْسٌ مَعْلُومَاتٌ
A’ishah said “In what was sent down in the Qu’ran ten suckling’s made marriage unlawful, but they were abrogated by five known ones and when the Prophet ﷺ dies, these words were among what was recited in the Qur’an.”
أَنَّهَا قَالَتْ كَانَ فِيمَا أَنْزَلَ اللَّهُ ﷻ مِنَ الْقُرْآنِ عَشْرُ رَضَعَاتٍ يُحَرِّمْنَ ثُمَّ نُسِخْنَ بِخَمْسٍ مَعْلُومَاتٍ يُحَرِّمْنَ فَتُوُفِّيَ النَّبِيُّ ﷺ وَهُنَّ مِمَّا يُقْرَأُ مِنَ الْقُرْآنِ
