"Do you have any food for breakfast?" and we would say no, so he would say: "I am fasting." One day he came to us and we had been given some Hais. He said: "Do you have anything (to eat)?" and we said: "Yes, we have been given some Hais." He said: "I started the day wanting to fast," but then he ate. (Using translation from Nasāʾī 2324)
كَانَ رَسُولُ اللهِ ﷺ يَجِيءُ وَيَقُولُ «هَلْ عِنْدَكُمْ غَدَاءٌ؟» فَنَقُولُ لَا فَيَقُولُ «إِنِّي صَائِمٌ» فَأَتَانَا يَوْمًا وَقَدْ أُهْدِيَ لَنَا حَيْسٌ فَقَالَ «هَلْ عِنْدَكُمْ شَيْءٌ» قُلْنَا نَعَمْ أُهْدِيَ لَنَا حَيْسٌ قَالَ «أَمَا إِنِّي أَصْبَحْتُ أُرِيدُ الصَّوْمَ» فَأَكَلَ خَالَفَهُ قَاسِمُ بْنُ يَزِيدَ
