It was narrated from 'Aishah that the Messenger of Allah came to her and said: "Do you have any food?" and Aishah said: "O Messenger of Allah, we have been given some Hais". So he called for it, and said: "I started the day fasting," then he ate.
This hadith also shows us how important hospitality is in Islam; Aishah was willing to offer her food to the Prophet even though she did not have much herself. This teaches us that we should always be generous with what Allah has blessed us with and share our blessings with others whenever possible.
