Mu'ammal narrated to us, Sufyan narrated to us, from al-A'mash, from 'Umarah, from Abu 'Atiyyah, who said: We said to 'Aishah: "Two men from the companions of Muhammad, may Allah bless him and grant him peace, one of them hastens the Maghrib prayer and hastens the breaking of the fast, while the other delays the Maghrib prayer and delays the breaking of the fast." Then he mentioned it.
