Sunan an-Nasa'i Book 22, Hadith 236
← Previous Hadith "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.

Sunan an-Nasa'i Book 22, Hadith 235 Next Hadith → "Do you have anything this morning that you can give me to eat?" we would say no, and he would say: "I am fasting." Then after that he came and she said: "I have been given a gift." He said: "What is it?" she said: "Hais." He said: "I started the day fasting," but then he ate.
