وَعَنْ عَائِشَةَ رَضِيَ اللَّهُ عَنْهَا
قَالَتْ: دَخَلَ عَلَيَّ النَّبِيِّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ ذَاتَ يَوْمٍ فَقَالَ: «هَلْ عِنْدَكُمْ شَيْءٌ؟» فَقُلْنَا: لَا قَالَ: «فَإِنِّي إِذًا صَائِمٌ». ثُمَّ أَتَانَا يَوْمًا آخَرَ فَقُلْنَا: يَا رَسُولَ اللَّهِ أُهْدِيَ لَنَا حَيْسٌ فَقَالَ: «أَرِينِيهِ فَلَقَدْ أَصْبَحْتُ صَائِمًا» فَأَكَلَ
The Prophet (sallallahu alayhi wa sallam) came to visit me one day and asked if I had anything. When I said I had nothing he replied, “Then I shall observe a fast.” When he came to me another day and I told him I had been given a present of some hais* he said, “Show me it, for I began the day fasting.” Then he ate. *A mixture of dates and clarified butter.
