It was narrated from 'Aishah, the mother of the Believers, that the Prophet used to come to her when he was fasting and say:
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.
