Musnad Ahmad 1153:1381

Muhammad ibn Ja'far narrated to us, Shu'bah narrated to us, from Sulayman, who said: I heard Khaythamah narrating from Abu 'Atiyyah, who said: We said to 'Aishah: "Indeed, among us are two men from the companions of the Prophet, may Allah bless him and grant him peace; one of them hastens the breaking of the fast and delays the suhoor, and the other delays the breaking of the fast and hastens the suhoor." He said: 'Aishah said: "Which of them is the one who hastens the breaking of the fast and delays the suhoor?" He said: I said: "It is 'Abdullah." She said: "That is how the Messenger of Allah, may Allah bless him and grant him peace, used to do."
