Lady Aisha (may Allah be pleased with her) narrates: Once the Prophet Muhammad (peace be upon him) came to me and asked, "Do you have anything (to eat)?" I replied, "No!" The Prophet (peace be upon him) said, "Then I will fast." Then one day he (peace be upon him) came to me, and he asked, "Do you have anything to eat?" I replied, "Yes!" So the Prophet (peace be upon him) said, "Then I will eat, even though I had intended to fast." The chain of this narration is Hasan Sahih (good and authentic).
