Hadith 10:85
‘A’isha said that in what was sent down in the Qur’an ten known sucklings made marriage unlawful, but they were abrogated by five known ones, and when God’s Messenger died these words were among what was recited in the Qur’an. Muslim transmitted it.
وَعَنْ عَائِشَةَ قَالَتْ: كَانَ فِيمَا أُنْزِلَ مِنَ الْقُرْآنِ: «عَشْرُ رَضَعَاتٍ مَعْلُومَاتٍ يُحَرِّمْنَ» . ثُمَّ نُسِخْنَ بِخَمْسٍ مَعْلُومَاتٍ فَتُوُفِّيَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ وَهِيَ فِيمَا يُقْرَأُ مِنَ الْقُرْآنِ. رَوَاهُ مُسلم
