حَدَّثَنَا أَبُو سَلَمَةَ، يَحْيَى بْنُ خَلَفٍ حَدَّثَنَا عَبْدُ الأَعْلَى، عَنْ مُحَمَّدِ بْنِ إِسْحَاقَ، عَنْ عَبْدِ اللَّهِ بْنِ أَبِي بَكْرٍ، عَنْ عَمْرَةَ، عَنْ عَائِشَةَ، ‏.‏ وَعَنْ عَبْدِ الرَّحْمَنِ بْنِ الْقَاسِمِ، عَنْ أَبِيهِ، عَنْ عَائِشَةَ، قَالَتْ لَقَدْ نَزَلَتْ آيَةُ الرَّجْمِ وَرَضَاعَةُ الْكَبِيرِ عَشْرًا وَلَقَدْ كَانَ فِي صَحِيفَةٍ تَحْتَ سَرِيرِي فَلَمَّا مَاتَ رَسُولُ اللَّهِ ـ صلى الله عليه وسلم ـ وَتَشَاغَلْنَا بِمَوْتِهِ دَخَلَ دَاجِنٌ فَأَكَلَهَا ‏.‏

It was narrated that 'Aishah said: “The Verse of stoning and of breastfeeding an adult ten times was revealed1, and the paper was with me under my pillow. When the Messenger of Allah died, we were preoccupied with his death, and a tame sheep came in and ate it.” 1: These verses were abrogated in recitation but not ruling. Other ahadith establish the number for fosterage to be 5. Translation Not Available
