Sayyidah Aishah (may Allah be pleased with her) says: I went out with the Messenger of Allah (peace and blessings be upon him) for Umrah in Ramadan. The Messenger of Allah (peace and blessings be upon him) broke his fast while I fasted, and he shortened the prayer while I prayed it in full. I said: O Messenger of Allah, may my father and mother be sacrificed for you! You broke your fast while I fasted, and you shortened the prayer while I prayed it in full. He (peace and blessings be upon him) said: "O Aishah, you did well."
