الكبرى للنسائي:٣٢٦١ – أَخْبَرَنَا مُحَمَّدُ بْنُ بَشَّارٍ قَالَ حَدَّثَنَا عَبْدُ الْوَهَّابِ قَالَ حَدَّثَنَا خَالِدٌ عَنْ يَزِيدَ بْنِ عَبْدِ اللهِ بْنِ الشِّخِّيرِ أَنَّ عَائِشَةَ «§صَامَتْ يَوْمًا فَجَهَدَهَا الصَّوْمُ فَأَفْطَرَتْ» فَقَالَتْ حَفْصَةُ لَأَذْكُرَنَّ ذَلِكَ لِلنَّبِيِّ ﷺ فَقَالَتْ

عَائِشَةُ لَا تَفْعَلِي حَتَّى أَكُونَ أَنَا أَذْكُرُ لَهُ فَأَحْسِبُهُ أَمَرَهَا أَنْ تَصُومَ يَوْمًا أَوْ يَوْمَيْنِ
